The best way to sort out balance and unit stat issues would be for Gearbox to solicit advice from people with the most experience playing competitive HW/HW2 and labbing strats/builds. Get their suggestions before making changes, and have them playtest fixes before release. That way you can zap obvious, avoidable problems (e.g., bc effective range discrepancy) before they mar the game.
The sharpest, most analytical HW2 vets I know played for years on GameSpy (may it rest in peace.) Specifically, I’d recommend Hideki, Cloaked, Madman, AOHNH, BlackBaps, and P5ynergy as top shelf smarties who could provide expert advice. Not coincidentally, most of them showed well in the few tournaments that have been held so far:
There are some interesting unit/balance debates in the forum, but I feel great sympathy for any dev trying to read through them all to separate the wheat from the chaff. Vastly more efficient to identify players with expertise and get their direct input.
