Wow, I seriously hope you are trolling or being sarcastic.
Bringing a non-balanced game to the competitive scene is unrealistic.
I can't say what will happen with Relic's attempts at entering the competitive scene. But there are tournaments now ( I don't need to tell you that I guess), and a ladder. Therefore there is some level of competition even in this state. So really it's just a matter of the player's perspective of "what is balanced enough" to get them to stick around.
That being said. I don't ever expect this game to be statistically balanced on all maps for every possible commander choice. Do you honestly?
The population is going down as we speak, I don't have the table with me but VonIvan posted it somewhere.
Rethink your answer.
The population for the vast majority of games out there follows a decaying exponential curve broken up by peaks of activity with the release of new content, sales and school vacations.
Here's the steam chart for CoH2: http://www.steamcharts.com/app/231430
The exceptions to the rule are the likes of TF2, Dota2 and CS:GO.
The only realistic goal for Relic is to make that decaying curve as flat as possible while introducing meaningful content in order to bring in new players.
