Granted rain seems to be getting used in every map these days, but it’s usually there for atmospherics, and it’s MEANT to obscure visibility!
Perhaps you’d like all maps set in the daytime and to not have buildings and other pesky things to obscure visibility? 
Finally though, I simply don’t understand where people get this misconception that rain affects framerates dramatically.
Even on the crappest of computers / graphics cards, disabling it is likely to have maybe 3-4 fps difference AT MOST.
Try it - stand still, let FPS settle. Disable rain. Don’t move. Compare FPS. Realise it makes bugger all difference :/[/quote]
I’ve a 700Mhz and i’ve already done this test.
And in certain place : i don’t move, i’ve 10FPS then i disable the rain and i’ve got 30FPS !
So for me the rain really affects the FPS.


but it could possibly work as last map, when everyone has maxed out skills, then some team may be able to break through even if the teams are uncoordinated enough that half of the team just runs around without knowing anything
