A game that forced you to farm in order to get all the heroes/spells etc... isn't competitive at all.
Cause you don't have the same cards that the others, It's unfair.
Arenanet gets it, and that's why I follow GW2 so closely ...
The real competitive people would make sure they BUY all the champions that they need in order to be competitive. Or you can continue being casual and play the free heroes. Your argument is invalid.
