I do have to wonder, why is Summon Bahamut on a 30 second recast? When you think about, is there truly a scenario that would enable you to somehow Summon bahamut in less that a minute after just summoning it? Though the reason I do bring this up is I wonder if the following would serve to make dying less painful. While it may have to alter the dmg potency of Summon bahamut, I do think it might work.

Basically, you put "Summon Bahamut" on a 2 min recast, However, rather than needing to use "Dreadwyrm Trance" twice to gain access to it, you instead just need to use 3 Aethertrail Attunement to Summon Bahamut. So Bahamut works as normal, cept now it's a 2 min recast, it's something you can open with however whenever you do go into "Dreadwyrm Trance" it reduces the recast of Summon Bahamut by 30 seconds. So there would be opportunity to summon it sooner if SMN builds up their charges quicker. Though I'll be honest and say the recast reduction may have no difference unless it was over one minute.


TLDR. Summon Bahamut uses the 3 stacks of Aethertrail Attunement rather than 2 "Dreadwyrm Trances". Dreadwyrm Trance serves as a way to reduce the recast of Summon Bahamut(2 min recast). Idea is dying becomes less punishing since you don't lose the built up Dreadwyrm Trances now that Summon Bahamut is tied to Aethertrail Attunement rather than the trances.
