by removing the dps check you remove the measurement of a dps role. U can make a party of tanks and healers, and maybe a bard to play the mana song. Yea i know this is the other extreme, but by removing role requirements, you remove the need for a role.

Thats not true!
Classic: This is the origin of MANA or STAMINA bars... For longer Fights then Potions were added.
If a Tank is "tanking" - no Damage on Enemy
If a healer is "healing" - no Damage on Enemy
So, how a Damage Dealer becomes useless?

Seriously, just removing DPS checks will not solve the problem, but it is the first step into the right direction, people like to have classic roles and not some "all can all"...
It is possible to have "all can all" as proven in some other games, but then there were other restrictions as Elemtel weel or other things...

Edit: The Problem we have is that the tank dont have enough "time" to tank because aggro handling he needs to do damage and the healer can not focus only on healing because lengh of buffs there is a useless "in need" rotation (not damaging but also not healing)
