the main thing imo that needs changing is for bards, mainly they fact they cant be stopped unless applied with CC, caster v bards is just daft, they need to change it so that, bards can only interrupt casts if they are in melee range, you know, like melee do anyways, and also thought bards damage do more damage if they are close range, theres currently not a lot of reason for them to do this with casters cos they can stop most of their casts.
