IT didn't matter that Lohse had like 15 spells to play with because she only get to use 4 most of the time.
You are aware that without some boost you only have 4 AP per turn? And most spells cost 2 AP.
Would you like her to have 15 AP per turn? Certainly it would make your fights easier.
How about a "kill the lot of them" spell? For 1 AP?
The issue with mages is that they're the only fair and balance damager on your side because enemies don't know how to buff the same guy 100 different times before letting him hit a bunch of enemies and do a 100-0 combo with only one rotation.
(on the other hand, enemy mages get extended range and spammable source spell to make up for how weak their melees are from not knowing how to buffs)
You need to cast at least 3 different damage spells to be able to keep up with what a 2H damager can do with a single buffed attack.
An Impale-Fireball combo with 4 AP can't even deal 70% of what a single Rage-Crippling can do for only 3 AP after you get your first colored 2H weapon. Add in Battering ram for 4 AP as well and you already need another rotation to make up for the damage differences.
