I would love different skill trees that focused on one of the elements. Or even a skill tree that took notes from Ascian Prime and it's Annihilation spell which was mixing Fire and Ice spells together.

I had long entertained ideas to be able to summon the Barghest(or give to me as a damn mount) like in the 60 quest but under our control, or the inclusion of spells like Drain and Breakga which enemy THM/BLM have for some reason. Or even "Dark" spell lines or even a Death spell.

But I think all we are gonna get is an AoE T4 that can't proc TC.

Spell glamour system? Will only approve if my fire can be purple and my Flare can look like the Astro's Gravity spell.
