It would really depend on the map and your team, I'd imagine.
I think the typical expectation is to hold A/B or B/C since you spawn in either A or C and B is the next closest Flag. But it would also make sense to get A/C, as B is a hotly contested flag usually in an exposed section of the map. Doing so, you might trap the enemy in the middle of the map.
With Dom, all you need is two flags and the win is pretty much guaranteed.
I think it really depends on the team more than anything else. If your playing with an organized bunch of guys and you commit to an A/C combo then it might be ideal. If your playing with randoms and you and a buddy are running back and forth from A to C flipping spawns like crazy while your other teammates are getting gunned down trying to obtain B unmanned than yeah. Its not ideal.
Depends on the map/flag layout. On a map like Warhawk or Whiteout B and a home flag so you know which end the enemy are spawning. On Flooded or Strikezone just play musical flags and run around capping all the flags.
There are some maps with flags you don't want to get, capping these flags makes it damn difficult to get round if you get spawn trapped
Stonehaven - B
Prison Break - C
Containment - C
When playing with my team we will not touch these flags unless it's near the end of the game or the enemy team is really bad.
Most people want to only hold two flags (A and B or B and C) because that team wants to control the spawns so their K/D is preserved. It's extremely boring and I hate when teams play like that.
If your really want to destroy the enemy team while having fun from the constant running around, triple capping is the best thing to do. The rage quits are priceless.
2 flags your team
Enemy one team. Don't go to close to the flag. That will force them to spawn somewhere else and than they can take a flag from you.
And which flags depens on map. Stoneheaven you want A and C. From A you can cover 3 ways from the B flag from one spot. 2 of those ways even within your FOV without looking around. (the small tunnel with stairs) and the side of the map. From same building you can overlook the gate.
On prisonbreak A and B are easiest to protect. B from the hill and A tower
Warhawk A and B is easier in my eyes.
And I will try to triple cap. Like to win with a biggest lead I can get.
Some maps are better triple cap still easy to protect.
other hards. Freight for example. When you have A and B try to cap C they spawn near A.
Other maps they spawn in location not near flags so when your team defends good you can hold the flags for long.
Other note: A lot of players don't care about caps
Its subjective... You can win games just by holding A and C, but holding two flags one of which being B will often makes it easier...
Depends on the map and what the B Spawns are... Strikezone for example. B spawns - 2 in bar, 1 in kitchen, 1 front door, and 1 back door... You could easily hold A + C and control the map... Personally, I would rather hold A and B... C Spawns - 1 pro shop, 1 statue, and 2 spots by the original starting spawn. C is the easiest to control... Either way, both strats will work...
However, a map like Overlord, its best to hold B as one of your two. There are no B spawns on that map - B shares both A and C spawns...
If you have a good team vs another good team - more often than not, it will come down to who controlled B the most...
Again, its subjective. With map, skill of opponents, etc - all playing a role...
You tend to want to break the map into two parts: your team's part and the enemy's part. So, on a map like Freight or Warhawk go for A and B or B and C. This way you can push the enemy team into their base/flag and it's much easier to defend your team's setup. Of course on Stonehaven and Strikezone, it's good to have A and C since it's easier to hold a team in their B base on those maps.
It's usually the beginners who triple cap, almost always if you triple cap you will lose the other two flags or nearly lose them within seconds, because opponents will re-spawn all over the place. I always catch our spawn flag and go for B and try and hold B. It's when you have a beginner who insists on going to opponents flag and capture it and then the game goes to crap.
Honestly, yes it does. You do not always want to go for A/B or B/C since B is the middle, it may not always be the closest to another point. You need to make sure that when you capture one, you are going to go for the other one that is in a tactical position to move from one another for a constant team effort of maintaining those flags.
Here are a few of my party's opinions (they are obvious probably but maybe wrong as well?) about maps that you should have specific sides and such.
Ones that we always do for sure
Stonehaven - yea A/C you can just camp all castle entrances
Prisonbreak - yep A/B
Siege - A/B - it seems like half of the map occurs BEFORE the C spawn, lol
Here are ones we usually go for but don't actually have valid sources proving correct.
Whiteout - AB, it's closer to B than C is, and the B entrance from C side has much better visibility than the trees and hill on the A side entrance
Stormfront - AB, again, it is much closer and the A/B building is easier to control than the C side
Octane - CB - you have the broken corner perch of the C building and then you have the Gas station roofs, they can see deeper into the A side than the reverse.
Chasm - A/B - the A side seems to cap B easier since there are initially only 2 major entrances for the C people to show up from, whereas the reverse has 3 major entrances
These are the ones we would like to know officially ourselves if there is an answer
Warhawk, I honestly prefer C side more because I think it's easier to defend C flag from that side's window building.
Strikezone - we've always done AB with reliance of sentry guns down the main two avenues while camping the Kitchen and Bar entrance on the far end by C, but I can totally see how AC just makes more sense.
Tremor - we usually do well KD wise on this one but it's just a rotation of which two flags we have
Flooded - A/C - 3 people defending each, both on the same side of the street
Sovereign and Overlord are two much like tremor we don't really know which is best to have. But having B is best for both I would assume.
If anyone has info on the new maps that would be cool too
