It occurred to me straight away that the change to Randoms; mandatory 1 tank , 1 healer and 3 DPS per run is a mathematical nightmare that cant be solved - DEVS please switch it back before we all go insane.
Lets look at some maths - lets assume there are zero players queuing for RLQ at my calculation start point.
Lets assume 5% healer toons, 20% tank toons and 75% dps toons.
So lets assume the first 15 to queue are all dps [double expected norm] then 2 tanks join the queue then another 5 dps then a healer joins.
Queue pops for 3 dps, 1 of the tanks and the healer who joined just now.
But hold on this only reduces the queue down to 17 dps and 1 tank and the cycle begins again, where there is NEVER going to be parity between the number of healers required and those queuing who are DPS. Because more DPS are joning the queue ALL THE TIME than healers or tanks - disproportionally.
For this to work there would need to be 20% healers, 20% tanks and 60% dps.
Mathematically this is a right forking mess. It really hasn't BEEN THOUGHT THROUGH. Oops sorry for caps.
