Have the balance of KI Season 3 been really figured out?

Hi there. I found an article really interesting about balance that I would like to share with you guys:

Are we leaving games before we fully figure out their balance?

This article sparked some questions to me regarding KI as it is now. I think that, over almost 1 year of Season 3, we still don’t know the true balance of the game. We got and will receive more new chars and this will change things, but I think KI should pass for a ‘maturity’ point. We should let Season 3 to roll for more 1~2 years so we can better comprehend its metagame. There are tons of strategies awaiting to be discovered, and this could change ( for bad or good ) our entire perception of the game as it is right now.

I would like to hear your opinions about this matter.
