Really big slow after anything you do
Everytime you cast any ability or either use auto attack as mage, you get a 90% slow for 1.75 seconds while everytime melees use auto attack they do a jump, and bows can literally jump after auto attacking.
Applying slow when you hit
You get hit by bow/melee and you are slowed 1.75 seconds, but guess what, you hit someone with magic attacks and he can still run like nothing happend, while you are slowed for performing that attack xD good luck chasing someone as mage.
Mortal empowerment
Mage is the only dps that can’t benefit from the most powerful perk for dps. Flamethrower kills and dot kills doesnt count for the perk (ice storm is dot). I’ve been 30-0 in a opr and still didn’t had 15 stacks.
Weapon Perks
What about the perks, they are adding damage perks that are only useful for ranged/melee weapons. Thwarting strikes, attunements and enchanted are good for dps that do damage as auto attacks, but mage cant benefit that much from them.
Weapon crit multiplier
Every dps weapon have 1.3 to 1.4 crit multiplier, but fire staff have only 1.25. With the resilient system sometimes you hit the same as critical than a normal hit.
Lack of cc
Every weapon have ccs, every dps weapon can stagger or root or even stunlock you to die like blunderbuss. Mage have 1 second root, if you dont miss the 1 try heavy attack, and they can dodge while rooted. Also if they have freedom its less than 1 second xD
Weapon tree
Just compare the passives of any other weapon to fire staff weapon, most of the perks are for getting more mana xD
With this im not saying to buff everything, but im saying that somehow mage cant benefit from anything in this game, would be nice to give him 1 thing to be good at, and that thing should be burst. I would change meteor shower to be only 1 meteor and do a lot of damage, also change pillar and make it a little bigger, or instead give it a little more damage.
