this has been touched on with ping-ponging and stuff, but i feel that i should mention that this a poor idea specifically for the source material;

alliance raids have three tanks, and none of them share a party.


You cannot shirk your co tanks.

you cannot see their emnity.

if youre an OT, you can't see the MT's enmity.


and while it's not particularly *hard* to tell if the MT is dead or not, and to see it's now rampaging through the clump of 22 other players, so you should probably 'voke.....

not being able to know/tell instantly at a glance if the boss is on a tank or not when the MT dies does add a second or 3 to the reaction time.

im certainly not going to ask anyone to memorize every tank's name they get matched with in their 24 mans. alliance raids just suck all around for tanking in general. theres a lot of just basic requirements for tanking that are just... ripped away from us in those.
