Mountaingoat,
You're overlooking the fact that advies have had tools intended for tanking for a long time. It should be no surprise that they still have these tools. They even had (shock horror) AoE taunts.
All that's happened here is that the tool has changed. Has it gotten better in some areas? Yes. Has it only gotten better? Absolutely not, there are a vast amount of sacrifices that advies have had to make to get these changes.
Consider the healing power (damage mitigation and aggro) that adventurers currently have in dragon form. Consider the AoE taunting ability from 3 nukes. Consider the evades boost they get from their buffs and auras. Consider the damage boost from same.
If you buffed a dragoned advy with RRFE and more ACs, they would be a better tank in terms of damage mitigation than the new tank form. They would have better evades. They would have better damage. They would also have similar (not as powerful) AoE taunts. BUT, the difference would be wholly made up for in healing agg... and yet, next to no advies actually do this...
Why?
Because they can do it better in other forms. And yet... You STILL don't see advies tanking any large encounters.
If low-powered emergency AoE taunting made such a difference and the new proposals for tank morph were anywhere near the level that has been suggested in this thread ( ) then you would see a lot more advies already doing this.
All that has happened is that the tanking form has been given some boosts at the drastic expense of pretty much everything that's important for an adventurer now.
If you think Keepers or MAs should get more taunting power. Great. I'm sure a lot of people would be happy with that. But it has nothing whatsoever to do with adventurers and you should take it up with the Keeper/MA profs.
If you think Advies will even come close to the abilities of Enforcers or Soldiers... well I'm afraid that's just silly.
