What's the point in having scenery if it can't be used in battle field tactics because some people can bypass its effect entirely?
I hate players having an unfair advantage, its like having a wallhack, or bushhack in this case, it detracts from the variety of game-play elements that make the game more enjoyable for the majority, maybe map editors should remove bushes in their entirety and make maps more boring and hiding in bushes a thing of the past, because their tactical use has been negated.
It's understandable that some player have incredibly shit computers thus want to make the game as playable as possible, but unfortunately in the world of gaming, the way to play games your computer can't handle is to consider upgrading your computer, you shouldn't just making new games look shitter and shitter just to be able to play them, first in multi-player games it encourages unfair advantages, and secondly you won't actually be experiencing the game how it's meant to be experienced thus detracting from your own experience.
