A direct hit at point blank does ~130-140 damage. That'll take out scouts, snipers, spies and engineers without the cool robot hand. Now, just outside of flamethrower reach it does 80-100. If you can hit a scout twice that close, the scout sucks. You shouldn't be able to get that close to a sniper, the engineer should be next to his gun and not worry about it, and the spy has everything to his advantage (cloaking, DR, backstab, faster movement, revolver that does 60). And if you complain about crockets, you should also be complaining every time that damn natascha heavy gets crits, or pyros, and crit stickies and spam nades. Oh sure at pointblank surprise, the DH has its one advantage. Have you ever tried using the lucksman? One click headshots for 250+ damage?
No I hate them because spies rely on a completely broken and proven unfixable mechanic called backstabs. And scouts have those freaking annoying sondbytes that I want to permanently remove from the game. I hate that prick.
