true exile, true, but then you don't need what people tend to class as a sniper marker, which tends to be low capacity scoped markers, Gommie will conceed that a scope (as apposed to a red dot sight) is all but useless on a marker. There is also little point limiting your capacity in your hopper unless the rules require it or you like playing that way.
There's nowt to stop you taking single considered shots from concealment with an ego, round paintballs are fairly limited for accuracy anyhow. With the automag I used in the past I was hitting a player at 100 yards regularly - at the end of the game he showed me the 10 that had rolled down his clothing into his pocket un broken, thats when I gave up trying to "snipe".
Plus if you are using something like an ego there is nothing stopping you cutting down that bush he's hiding behind!
