Focus on other things besides balance
I agree with the balance, was ok before patch and after patch as well. It only shifts things up. But my opinion to become successfull is quite different:
To become esport, we first need a serious tournament system like in gw1. Daily automated tournaments to qualify for a big monthly tournament with unique prices, thats what we basically need. Something to compete with others in a serious environment.
The foundament needs to be done. Casters, viewers, community tourneys, maps, modes and all that stuff are just nice addons in the end, and will follow on their own by success.
