No, Because you will just exploit the game mechanics more than you do now.
It seems your lack of skill and the haterd of turrets exists because turrets are the only thing that slows down weak assed offline trash players from raiding a base faster.
Your ideas can all be exploited
Just hide behind a bush and rocket spam a base, you cannot remove bushes short of planting a foundation on them
Pop multiple smokes and rocket spam a base or plant c-4.
All guns shoot through water but remove the ability and no water base is safe. You can swim up and get in with no real effort.
Turrets are nerfed enough for the short bus riders usually allowing you to get hit and walk away heal and rethink your approach. Turrets are very much nerfed especially for a electomechanical device that woule be supremly accurate. They should work as well as the weapon and ammo in them but they do not produce the same amount of damge or range.
If you hate turrets so much make your own server and remove them.
