I have, like, no faith that SE is reading this. But if they are, I'd like a change to SMN.

Summoning an egi applies a buff on the SMN, lasting until the summon despawns. The debuff changes the DoTs and Fester's actions.

Ifrit-Egi:

Miasma, Bio and Bio II become direct-damage attacks (dealt by Ifrit-egi), instacast but with their cooldowns equivalent to their cast times. Fester applies all three DoTs instead.

Garuda-egi:

Classic Warlock Summoner play, Wind-aspected.

Titan-egi:

Various emnity-raising skills executed by Titan-egi. Fester casts Bio, Bio II and Miasma instead.
