Very overpowered. A team of snipers can wipe a map easily. Not only does it boast One Shot Kills, it covers an immense range of painted blocks. (About a 5 block wide area spanning the range of the shot, which is relatively long, since it's a sniper). I suggest we focus more on the One Shot Kills than painting blocks with this weapon. Firstly, increase the range. Secondly, decrease the cooldown, just by maybe a quarter of a second. Thirdly, decrease the amount of blocks painted, this can be done by firing only a single snowball as the round, and only blocks under this snowball get painted. This should leave a single line of painted blocks, rather than a 5 block wide path of destruction. This also gives a use for the slime on the second sniper kit, for when they do wanna paint blocks.
