Ion has said they want to relax the class design adding more spells and also make more spells class wide.
What changes would you guys like to see?
Me?
Arcane Explotion baseline - Great for finding rogues and aoe tagging
Pyroblast being a big damage spell - I understand people enjoy current fire but Pyroblast should be this huge damage spell and it is just not. Maybe make a new spell fit where current Pyroblast is, and make Pyroblast something like Ebonblade, big damage on a cooldown.
Fire Shield and Arcane Shield are strange to me I wish they were more creative to make these specs have survivability than just giving a recolor of Ice Barrier.
More of the highly situational active spells in the PvP talents should be regular spells.
Other than that I think Mage is one of the least problematic classes out there right now.
