and in PVE the mechanics for tanking are not attractive to many.
This is my point, tanking in pve makes you a plaything for even weak mobs, and grabbing and keeping aggro is a pain in the ***.
Also there were already a lack of tanks queing for hmfp at 50.
Then devs nerfed the **** out of tanks AND buffed the crap out of dps and heals on the way to 55.
Why would i want to run on my underpowered totally dependant tank when i can be on an overpowered self sufficient healer or commando?
And to be clear i define power in tanking as the ability to resist damage and to grab and keep aggro.
