Suggestion to help class diversity in Ren'gol levels

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.

I wonder if it would be possible for a warrior skill to give out constant aggro? AFAIK, it does it in bursts so it's hard for the tank to keep aggro.

I also wish new gear would focus far more on hp and armor for tanks; hell, let there be two different versions of gear again, damage and hp for the PvP junkies, but if tanks are supposed to do their job, that is hold aggro - they'd need good hp for it, right? When I started AL my impression was that the tank would be unkillable and also not get kills; the only issue I can see with this is that heal is damage based.

Ok so the things I notice outside the fact that taunt sucks, hardly works/lasts, etc etc is that bosses (and possibly mobs) will generally attack the person who is furthest from them. So even if the warrior is right in front of the boss, the boss will go rush towards the ranged attacker or someone who is kiting. That's why one of the popular all rogue strategies is to stay on 4 different sides of a boss and fire arrows. I just hope we don't have to resort to these options soley.
