interesting discution..
i understand some "reluctance" with this talent
-if you take DG... you may be better positionned by your RL as a good OT with a great "oshit" tool which will help MT&raid
-at least, if you don't have DG... no interrrogation : you can pretend to be as well MT or OT
i may be biased because i'm our guild HL-Officer old raider, i don't have to fight for a seat. so i have DG
not because my main role is to be OT (and only MT when i'm the only one available), but just because it is a very nice tool, and even as MT, it might have some fight i will shine even more
i've yet to evaluate the counter part of not having DG in my template.
i think also we have to wait those specific fights&phase where DG can even be used when MT
PS
yes, we have a specific role as a tank, but we are also part of a raid.
we have a dedicaced objective as a tank, but we also have a general objective as part of this same raid.
