I enjoy playing BO2 but there a some things that, in my opinion, have a negative influence on the gameplay. Hopefully Treyarch will take them in consideration when they are creating their new CoD.
I mainly play Domination and these are some issues I have encountered.
First off the spawn system should be improved. Sometimes I am getting shot literally within 2 seconds after spawning. The main reason behind this is that the spawn system doesn't recognize where enemy players are located on the map when spawning. Treyarch also chose to spawn on teammates, which is not working out because when your teammate is in the enemies line of sight you'll most likely get shot as well. Another problem is enemy players spawning behind you when you kill them. I think that if the spawn system knows where enemy players are located on the map the spawns will work better and you won't be encountering previous situations as much.
Campers have been a problem since the first online shooter and I do understand that it's very hard for a developer to change the attitude of players. However there are ways to make the life of a camper a bit harder. For example their could be a constant UAV which does not show moving players, but only those who are not moving (same like how the ghost perk works). This might also reduce the amount of UAVs during a game but I will get to that later. Also because of all the objects the maps contain people find places to head glitch, something that I don't quite understand. How can a player aim over an object when only his head is poppin' out from the enemies point of view? This should definitely be looked into because it's a major flaw.
I believe the Target Finder attachment was designed to be able to spot not moving players more easily addresed but in reality it seems that it worked out the complete other way around and that campers are using it to spot anyone approaching them or trying to take them out form a distance with a sniper. Therefor it can be thrown in the bin and deleted so it can never be returned to any CoD. If you can't spot players without help you shouldn't be playing CoD at all.
I believe UAV should be a higher scorestreak. The main reason behind this is that UAV is more useful then streaks that require more score like Care Package, Guardian and Hellstorm Missile. Therfore the UAV spam is crazy at the moment (the fact that some big youtubers are praising non-lethal scorestreaks isn't helping either ).
LMG's are a bit overpowered in my opinion. I do appreciate that they have great damage output but that should be balanced by more recoil which is way to little as it is now.
I did not write this to bash Treyarch, like I said in the beginning I enjoy playing Black Ops, however there is always room for improvement. How do you guys feel about the things I mentioned and what would you like to see to take in consideration?
