Well I already reported another collusion incident in last 12 hours
(stupid fluff rule, purely an anti troll mechanism, understandably)
THUS far I have found a confirmed 3 sets of KR's possibly a 4th.
It's kind of a shame that TEAM/ALLIANCE/FFA etc....bleeds into express.

I propose EVERYONE be assigned a RANDOM name at start of game, that way you actually have to spy to figure out the bots.
