Spiny Plume should follow the last person that did damage to it. So it turns into a caster/ranged mechanic, something that Garuda EM lacks. It's even more boring than Garuda HM, where you have both sisters close to you and taking Slipstreams/Cleaves is a concern.

Crystal Tower is fine. Needs a tank mechanic on Acheron, though. Tank stacking for taking cleaves, or the good old tank swapping would be nice.

Revert certain changes to jobs. Medica II nerf, Scholar pets changes, Lustrate buffs, and enmity buff are the ones that bothers me. The game became very boring, fights like Ultima becomes easier if you just keep Medica II all the time, while tanking and DDing became braindead. Having to put scholar pets on Obey and then Heel when I'd like her to just blow her cooldowns as soon as possible is ridiculous.

Limit Break bar filling as normal. No need for explanation.

Crystal Tower lockout for Coil would be nice. It's the only place along with EM Garuda where I am pushed to play the full extent of my job, and would like to do it more.
