If your lucky enough to group with decent people the situation for those should be GREED for everyone , unless of course a player within the group says hey do you mind if i need for off-spec or companion.
Had a situation myself today pugged a SM EC , there was a Vanguard that joined as a Tank and myself on my commando dps, at the last boss when kephess drops the BH pieces he needs on the Aim pieces regardless of the fact they were clearly dps items , and when asked why he a Tank in Dreadguard / Campaign gear his response "I don't give a **** , DPS is my main spec , and what do you care its only BH gear ... i can need it so i will" keeping in mind that my gear is tionese/columi . Who should have won those ?
Fact is the system as is can work perfectly fine when not dealing with the above kind *****s. And unfortunatly they are becoming more and more common because theres no system in place to have something done.
