I don't know much about this e5 thing. What I write here is purely my imagination and don't even know if they are reasonable or a taxing job. So how about we have spells like tikes 2 to 3 turns to cast without letting you move, like grand heal, grand meteor shower, grand resistance debuff and some other less powerfull spells that also take 2 to 3 turns to cast but let's you move and jump. For multiplayer why don't we have like combined spells if you couldn't persuade your friend to let's say play fighter he or she insisted on playing warlock like you how about you use a unison spell to increase a spell firebolt to lvl 2 by using one spell point from each, and early on game tactic that is costing double the spell points unlike a learnt spell. And what about fighters have like combined melee attacks like double rush, or double lariat attack or smth.
