Sniper turrets were added by request, and have been a complete headache ever since.
Basically, if I set the range too low people complain they're not really sniper, have it too long they complain that it's too powerful
if I set it to fire as fast as a standard gun turret, people complain that's not really sniper, so it needs to fire slowly. but then it doesn't do enough damage. So I have to increase the damage multiplier per shot, but do it too far and and again, it's too powerful.
currently, it's around this middle spot, where it actually does less DPS than the gun turret, but with a longer range (though accounting for damage reduction per shot isn't easy, the DPS against smaller things is much lower, but the DPS against larger things is potentially higher)
So, I'm stuck in this position where SOMEBODY is going to complain at me no matter what I do, even if it's doing nothing.
Do nothing: people like you complain.
Reduce the damage: people complain it's not powerful enough
Increase the damage: People complain it's too powerful
Reduce the fire rate: people complain it's not powerful enough
Reduce the range, or increase the fire rate: it's not sniper enough.
Delete the sniper turrets: People complain that I deleted the sniper turrets!
So... what would YOU suggest I do to fix this, WITHOUT upsetting someone.
