Suggestion to help class diversity in Ren'gol levels

[Ravager]

I posted this in another thread but didn't want to threadjack (too much).

Rather than reducing stun (in ren'gol levels) I would like to see more things that will help class balance.

Add the ability for warriors Rally Cry to give user and teammates stun immunity.

Since the introduction of the class specific material gathering mounds, why not make altars that are class specific in rengol levels.

Warrior altar grants stun immunity for the team for x seconds.
Mage grants damage boost for x seconds.
Rogue grants dodge or speed for x seconds.

Its faster and easier to run solo with my rogue than with pugs right now. The reason is most of the pugs are warriors and sometimes mages. Although we have yet to see elite, I don't see anything this would do other than improve class diversity in maps. Otherwise, its all rogue teams yet again.
