I recently saw one Reaper killed by two Glaives. Reapers are clearly not powerful enough.
Seriously, this game has a GREAT REPLAY SYSTEM. If you can't take the time to link to the damn replay, then don't bother typing. Replays allow people to evaluate the CONTEXT of the event, not just "pyro beat outlaw".
Was one player better than the other?
Was there superior micro involved?
Was the player with the outlaw even paying attention?
Was there a bug?
We don't know because you can take the time to type up a post to whine about the balance, but can't take 30 seconds to link to a replay.
