Waiting on a tank or healer in LFG .. So why can't we 'fake 'the role with stats/templates? Not saying make the trinity completely irrelevant, rather if a specific role is not available after X min, allow a DPS specs to tank and heal?
This would need the DPS player to opt in of course, but after that and when said player accepts and enters the group, use template to buff mitigation (and lower dmg?) Same goes for a DPS class with healing, template the hell out of it so it can heal?
I might be using wrong 'words' to describe the idea though I hope at least it came across clearly?
