You're really not too bright are you? So while you're in a trance doing absolutely nothing for those 15 seconds you are limited to your 750 cure and a little tiny bit of damage mitigation. Let's run the numbers again shall we Junior? During that same 15 seconds of White Mage cast Asylum. 100 pure potency with a tick every 3 seconds for 15 seconds for a total of 5 ticks that's 500. During that time the White Mage is free to cast. What's a 1.85 second test time during that same 15 seconds a White Mage can get 8 cure 3s off. But for argument's sake I will use the numbers only for 7 just to make it fair in case I had a little bit of a leg or what not. 7 x 550 cure potency(3850) plus the 500 cure off of asylum = 4350 total cure pot over the same 15 seconds
Heres the numbers your measly little 1200 output vs the 4350 that's a White Mage outputs over the same duration of time. Even if I factor in that 10% damage mitigation the White Mage wins. Let me take the argument further since you don't seem to understand this. Let's say during that same 15 seconds one or two people died. You can't stop casting that or everyone stops receiving the healing. So White Mage could raise somebody in about one second flat if macro correctly. Still getting 7 of The Cure threes off but being more beneficial to the party at that point in time. I don't know why you want to keep making the argument that this is the best thing ever know it's never great when you have to stand still and channel the only time I have ever seen this used is in raids when massive AOE damage is incoming that is the only time that it has a beneficial use for this ability. If I decide to do dungeons I never use the skill in a dungeon because there is hardly ever a use for it or time for me just to stand still in one place for 15 seconds. However when I'm on the White Mage I use Asylum all the time. I don't care which one you think is better I'm telling you that anytime you have to stand still for 15 seconds it's not a good thing. Especially during dungeons there is so much happening that if you are the one that standing still for 15 seconds then chances are you are the one that I am constantly Reviving.
