the main problem is that none of you realise what OP is.

there are 2 signs of OP:

a n0ob can pick this up and be better with this than something else

for example.    A person who just bought the game, chooses Cutter, and gets owned.   However if he chose Anders, and owned the other person, then Anders would be OP.   This isn't true OP, this is just when something is better than something else because it is easier to use

the other sign is:

when a pro can use this much more effectively than any other thing. 

for example. the top pro chooses to do one thing because he can use that thing much more effectively than another unit

This is true OP. simple as that.
