You can change class in the waiting area between turns...

The biggest issue I see is people quitting after Turn 1 and leaving a surplus of tanks trying to Party Finder a Turn 2 group; these groups generally are setup by a tank allowing them a 100% Need on any Fending gear that drops. This double skews the loot distribution among players that are not in static Coil groups - and it generally becomes a self perpetuating trend as people demand high iLv - meaning endgame tanking gear becomes more exclusive; and the problem of finding a tank or a healer becomes more difficult.

Personally I've felt the negative effects of this; but the 0 Click method is more reliable, and requires less organization. If you're the one getting that coveted Tank slot it's actually really very nice.

March will change much of this hopefully and allow Tanks and Healers without dedicated statics a chance to catch up their item level - otherwise the disparity in well equipped Tanks/Healers would be perpetuated.
