If people game the EPGP system you talk to them and assure them their output is suffering on the short term. If they do not quit with it, you put them on the bench. Decay kicks in, and oops the plan did not work out. Really simple and very efficient. Especially in 25 man where people of similar specs know exactly what is a good upgrade for another person and what is not. Also, you can set the decay higher if you want to evade people hoarding EP.
Human beings are inherently biased to aspects such as "this person has been in the guild longer" and "this person is quitting soon" to "this person is performing better" (which may be actually scumbag DPS). It is very hard to keep track of everything in 25m. Loot council also makes raiders suck up more to the officer team, leading to a more top-down hierarchy.Anyone saying loot council is inherintly biased. No sorry the guild you were in just had an extremely poor leadership. Nevermind the fact that gear is not the Gold star award it is the mean to an end which is content completion. Then after this you can pat yourself on the back and collect more tools <gear>
