Too many classes have long-range weapons that would rape your expensive turrets if they had less health.
If anything, they could use more health. As they are right now, is fine. I forgot, the PC has a juice nerf right? In matter of fact, any turret changes may make camping horrible. Just leave them as is.
If you don't know anything about the thing you are talking about, don't talk about it. The juice nerf pretty much renders any normal turret killers unable to kill turrets, dragging out gigantic *** one-sided matches, where even if you are winning (dohoho), the shitty side can just hit your money ball once and win by their superior base due to them having to turtle for 15 minutes.
Correct me if I am wrong but I don't think the juice and turret changes are what causes players/team to turtle?
No, what's wrong with turrets, really? Nerfing and buffing randomly won't balance the game. Leave what's fine there.
