Everyone's opinion on how fun/enjoyable the game is matters.
Everyone's ideas on how to fix the game matter, unless they're insane.
Everyone's opinions matter but Relic has no responsibility to incorporate all our opinions into their game.
Not everyone's win/loss statistics matter when it comes to estimating the current state of balance. That isn't to say that lower ranked players don't matter, just that you have to balance from the top down. Looking at the win/loss statistics of the upper echelon of players is going to provide a more accurate representation of the current state of balance.

I know that would be an unpopular opinion on these forums.... But 1000 or even 5000 players aren't going to pay for a Relic to stay in business.
That wouldn't be my argument. Mine is for a bit more similarities in the factions that would allow for easier balancing (or at least less imbalances). And for more strategic choices like tech trees instead of commanders, and global upgrades. But that ship has probably sailed.
