*Fire mage dps ihas now plumetted, and shows no signs of stopping the descent. Dead last is soon to come. Examples:
Look around for yourselves. Seems we weren't overreacting.*
Disclaimer: I'm not arguing that fire mages or mages as a whole shouldn't be nerfed, in fact I believe that everyone should be on par with each other to create a much more competetive raiding environment, but this is obviously impossible. I'm arguing against a massive nerf into the ground and out of viability that was hotfixed sneakily and without any prior testing.
Anway, onto the meat...
Interestingly enough, our 22+ page thread on our class forum addressing concerns has been deleted. No feedback yet, however. Probably due to the lead systems developer stating that he doesn't read class forums anymore. Apparently developers actually read Damage Dealing because it offers very valuable opinions such as "cry more" and "I don't see what the big deal is" from people that have no idea how mages work because they have never touched them before, and are glad to see them at the bottom of the chart by virtue of their past success.
The periodic damage from Combustion has been reduced by 50%.
The critical strike chance multiplier from Critical Mass has been reduced to 1.25 (was 1.5).
This effectively brought fire mages from first to last overnight. Geared mages (item level 490+) are seeing at minimum an 8% (essentially 4600 or some odd critical rating disappearing) decrease in crit, causing a snowball effect calculating at 15-25% dps decrease. This is because it causes more casts of fireball/scorch that do not crit, leading to less usage of pyroblast, leading to pitiful ignites, and this coupled with the combustion nerf makes absolutely horrid combustion ticks (it is now on par with level 85 combustion ticks), not to mention it also nerfing our tier bonuses (+8% damage on a spell we'll be using a lot less often and -20% cooldown on a spell that just recieved a -50% damage nerf) all compounded screws us over. This makes us no longer viable for progression raiding.
According to http://www.noxxic.com/wow/dps-rankings/realistic-dps which is calculated using a beta simulationcraft build that supports the hotfix, item level 496 fire mages are now ranked last. Please note the blurb at the top of the page stating "These DPS estimates are based on a modified single target (no cleave) fight with regular movement, raid-wide stuns, and player distraction. This is a more realistic fight that highlights each specs maximum DPS under typical raid conditions. The Realistic DPS simulation is run across 10000 iterations with a variable fight length of 360 - 540 sec and a non-optimal use of raid buffs."
So obviously, while this isn't 100% accurate due to varying level of player skill, global usage, cooldown stacking, and RNG, it is still representative of the overnerf we just recieved.
