I know the teeth feature hasn't been out for long (1 week), but I'm sure plenty of you have your own suggestions.
I can't really think of anything though but wanna see what other people have in mind.
One thing they could possibly do though, in a discussion I made, I said about them speeding up the IMS because they are currently too slow. Maybe they could make us buy that. If it now takes 6 seconds for the IMS to shoot + hit the floor, they should let us buy the upgrade in which it would shave off 2 seconds, taking it from 6 seconds, to 4 seconds.
It could be a decent amount of teeth, such as 20, 30 or 40. I wouldn't mind, because it could make a huge difference.
Ok I thought of something else, so I will start a list now and keep adding to it.
That's not entirely true. Sentries cost a lot. And having 3-4 of them is generally enough. At that point having an IMS to lay down for a rhino or to cover the drill if you need to revive or something really comes in handy. Vultures also tend to work nice for medics.
An explosive ammo upgrade would be so OP...but I like explosive, so why not.
Stun ammo upgrade: Stun ammo is now also armor piercing. Stun ammo is useless, but if it pierced and stunned it would be better. Also, Stun ammo should actually slow enemies down, not just make them light up for fun. I really don't know what Stun ammo is supposed to do, but nobody ever uses it, so an armory upgrade is in order.
Some upgrades I wouldn't mind seeing...
1. 10% increase to all movement speed (sprint, mantle, etc). Cost = 15 teeth (?)
2. Use abilities while in last stand. Cost = 30 teeth (?)
3. Propane tanks do more damage. Cost = 5 teeth (?)
4. Decrease cost of weapon purchases by 20%. Cost = 10 teeth (?)
5. Lethal equipment can be primed and thrown 50% faster. Cost = 10 teeth (?)
I've included a (?) because those are the cost I believe they are worth, but the cost may differ to everyone else. Let me know if you think any of those are unfair costs.
