Dear Relic.
Do you need to hire more people? Do it.
Do you need more equipment for testing? Buy more computers, designate a room for "testing," and have your developers write balance testing and simulation code.
Does the balance team not play the game enough? Do it.
Do you not collect enough data? Do it. Hire a statistician while you are at it.
I somewhat agree. It does seem they don't spend nearly enough resources on balance. I'm sure it would be a good investment and if they were better at balancing, they could introduce new paid commanders to earn more money to fund the balance process. Currently I have no dea how they earn money since they're not taking any of mine or anyone else's it seems.
Katitof's point is correct - no matter how much testing they do, there will always be new problems. If they were on the ball and fast, they could fix those too and move forward. But they are so slow
Alos, yeah make the balance team play the game more.
