Not a bad idea, BUUUUT even with the OP stuff, very few players can beat the top players. Even if you made them more OP, they'd find it hard. How about the same idea but matching the players against another player of similar skill?
Exactly. What is the definition of OP unit? It's a unit that, let alone your skill, gives you a non-deserved upper-hand in the fight against your opponent (the opponent being of equal skill or very close in skill), fight which would be otherwise lost.
Secondly, related to the third point "If troll succeeds, thread stays open for further discussion", it's wrong judgement. If "troll" succeeds, than the unit should be modified. Period.
One single game it's not enough, sometimes even best players can have a bad day. There should be at list 3 games, and then a game between top 10 players.
Several tests must be made, in order to take the right decision. BUT: This is what Relic should do before "balancing" the game through patches. NOT US!!
