I agree with most all of that. I think it CAN work fine in a GT setting.
With that said, I am not planning to allow FW rules and units in any Singles events we have in the foreseeable future and when we run a GT we won't be allowing it the main event either.
Like I said before, I won't get into details but I just do not believe it is in the best interest of Battleground to do so. Several of the reasons have been touched on in this thread and I am all for the community discussing the pros, cons, ins, outs, and anything else they'd like about it.
