I'm interested to hear what others think are the major issues with mages in PVE right now / in the next patch.
I'll start with a few that have been bothering me lately:
* Weak at 10man - at least fire and FFB (and surely frost) feel very weak in 10man compared to melee or some other casters (like warlock). Didn't try arcane. Even when you get most of the caster raid buffs, it just doesn't perform as well as it does in 25man compared to other classes.
* Glass canon -
Melee have way more hp (some melee in my guild have over 30k hp raid buffed, i barely have 22k). This is something blizzard has been doing for long time since melee may take more damage in some fights. So lets look at the casters:
Mages - ice block and blink. can't use heatlstones. fire take 3% extra damage. magic absorption in some specs. low hp.
Shadow priests - can shield themselves , take 15% less damage (shadowform), dispersion, can heal if they shift form.
Warlocks - extra hp, drains, deathcoils, soul link, teleport.
Elemental - can self heal, have more hp , take a bit less damage (elemental warding).
Boomkins - barkskin, can self heal (requires shift - rare), a bit more hp.
In fights with a lot of raid damage (like Mimiron and Algalon) mages are at a big disadvantage to most of the other casters since you major advantages (blink and iceblock) are not enough to survive the massive raid damage you take throughout the whole fight. I guess a good way to sum it up is mages have some nice tool to avoid damage, however when they do take damage, they are the most squishy of all classes. Massive raid damage is added to challenge healers, and this damage is therefor often unavoidable, which leaves the mages at a big disadvantage in which we need to spec/gear for survival at the cost of dps.
