I like the idea behind the rework but I find the execution far from elegant.

DWT should really work like FBT at this point by passively integrating Summon Bahamuth in it since it feels clunky and unnecessary, especially after losing its damage buff.
Just like what happens with FBT, DWT should also temporary upgrade Ruin III into Wyrmwaves and Outburst into Death Flare, Enkindle Bahamuth could go for Mega Flare which is also Bahamuth's classic signature attack and would at least look different.

Egis are another point which overall seem like a half-executed idea.

Garuda is the only one which does what it is supposed to do: aoe specialist, has its niche, good.

Ifrit doesn't really need a weak aoe as Egi Assault II with the same potency of its single target ability, make it a full fledged single target specialist and give it a single target DoT instead.
If we need AoE we should just summon Garuda anyway, it's istant and free.

Titan has (finally) a good concept as a walking defensive cooldown but it still feels too punishing, and pointless, to use most of the time.
Allow Egi Assault to proc Ruin IV and remove the weak, useless, aoe from Egi Assault II and turn it into something for what Titan is supposed to do: support.
How about a Gaol on self that gives a brief invulnerability? A weak aoe Stoneskin effect for the whole party? Or maybe something for DPS, like a crit buff?
