Threads in this forum should be limited specifically to the balance of the game in multiplayer. Topics would include discussions about specific strategies, factions, or units that might "break" the multiplayer balance as well as proposed solutions to balance problems.
It is important that we all use this particular forum well. Relic will be using the beta to identify balance problems and come up with solutions. This is only possible if we, as a community, work together and discuss these issues in a constructive manner. Bickering about balance doesn't do anyone any good.
Remember, this is the beta. We're all on the same side and we all want the game to be as polished and balanced as possible on release day. Lets help the devs as much as we can.
