If they want to have roles, they should lock them in. In order to do so, they'd have to: 1. Change matchmaking to account for roles matching. 2. Disable collection of motes for those undesignated when a mote collector is present. Same goes for invaders. 3. Disable switching kit in the middle of the match but allow it while in the waiting area, so people could firm up their roles. (This would mess up the matchmaking suggestion, above.) 4. Reduce or stop giving individual bounties which conflict with roles. As far as having to run over motes 5 times to pick them up, that's lag, either yours or a team mates', perhaps even opposing team. Magnet effects would have motes flying in every direction when they're not actually picked up.
