Big AoE was the Arcane Mage one trick. They’re pretty meh outside of that.
In PvP arcane mage healers will be laughably easy to shut down. AM channel. Regen Channel. AB, long cast. Poly and blink same school as everything else you do.
They also are just OOM constantly. Wanding doesn’t transfer to beacon.
Adjustments I’d like to see for mage:
Give us a real res, not trash scrolls.
Buff our water or reduce our mana costs. Maybe give us retail style food/water summoning that’s % based. Living Flame and Arcane Blast seem like the only real decent options for arcane healing atm. If you nerfed AE AoE healing I have a feeling you’re going to butcher Living Flame next though.
Also, let use use arcane concentration procs on healing
