Agreed. I tank Drakes on this fight and its like a dance, its fun and challenging. I think I've got it down pretty good and if only we could get people to stay out of flame walls and swirlies, we'd have it licked.
(This is why Sartharion is fun as a drake or adds tank, because there's so much to react to rather than simply the mob in your face).
I like this idea alot because it puts the decision in the tank's hands instead of robotically mashing a button whenever it lights up and staggering CDs to always have something going on. It 'feels' right to know you have to hunker down because you assess a situation or a problem and while you don't have to blow shield wall on a wipe and go without the next time, once you use it, its gone. So you are forced to use it wisely.
I think "big" cooldowns being on a 3-4 minute timer is a nice sweet spot that allows tanks to use things reactively in the fight to relieve stress or save a wipe, but not encourage or enable the dangerous linking of permanent cooldowns.
Something Cider has said in the past is that you should never die with a CD up. I can live with that as long as it is understood there are situations where you might as well keep it holstered. Sarth 3D, first Flame wall eats 7 people, yeah, go ahead and wipe it. Its not as punishing to go ahead and blow them these days and I think that's just right. I wouldn't mind seeing them handled exactly like health potions. Once per fight.
your hat may be nice, but I have the little white tank top that says Legendary right across my boobs. I win. (or more correctly, H wins)
