So just cheat, dual log as you wish, who cares how much mercenaries or scouts someone has or troll characters in fact, the only real problem that bothers me is FR and current usage of it. Everyone uses scouts, some slaves on WM or mercenaries, looters and whatever on dual logs, that hasn't bothered me never and ever, i myself use 2 windows of clients constantly and have been using forever. It is so easy to set up that dual log, that i couldn't argue that it somehow gives an advantage since every team use that, if someone don't it's their loss. (i simply don't consider that as cheating how common is that, maybe it's stupid, but not as stupid as 5 combat characters ready on WM)
Stupid game mechanics provokes us to do that (30 man swarm around the corner, impossible to notice them unless someone dies), i had suggestion to even somehow ease up that scout situation, by using motion sensor mark II as static scouts witch reveal area around the map and with right availability it should work just fine, but instead we have some developer saying it's against the rules, maybe do something about it not only declare some lame ass rules that has no real weight behind them because it's impossible to enforce them conventionally.
