Hi Everyone,
I’ve been seeing a lot that Fire mages seem to be really strong in M+, especially so on trash pulls. I’ve been struggling a lot on trash and I was hoping some folks can share some tips on what they do on trash to carry their own weight in M+ dungeons.
The basic rule of thumb is if it’s packs of three or more combust and flamestrike. If combust is on CD flamestrike whenever you can off procs. Use dragon’s breath too especially on mobs that need to be cc’d. You can also use arcane blast now that we have that back, but only when everything else is on cd. Make sure you are also running the talent flame patch. Oh, lastly if you’re night fae after combust and fire blast is on cd you can pop shifting power, it’s a decent AOE + it reduces the time left on your cds. So essentially it should reset your fire blasts so you can proc again when heating up. Hope this helps 
Hi buddy, i’m a casual fire mage but i’ll let you know a bit of what i know. You should use flamepatch and combust on cooldown (usually try to comunicate with you tank when combustion is available to make bugger pulls and take advantage of fire mages great dmg).
Fire mages are kindly dependant on two things, which are: pulls and combust. You will always want to dump combust on trash while fortify is active. On tyranical you would always want combust on boss, so timing of your cds is very importan.
Skill priority for flamestrike is as follows:
Hardcast flamestrike on 3+ targets if combustion is on cd
Combustion aoe rotation should look like this: combust - fire blast x2 - flamestrike - nightfae ability - fire blast x2 - flamestrike and use pheonix for ignite
Try to get infernal cascade conduit since it is great for Aoe and st. Also firestorm legendary is great when it procs.
Remember mastery is good for aoe while it loses value on st.
Those are basic things you should know to keep a good overall dps on dungeons.
Hope it helps a bit.
Honestly I’ve had better results as arcane in Mythic plus right now. For fire to be good with the current stats you really need to talk with your tanks for thicc pulls.
Flame strike spam with low haste is really sh*tty, so if they can group more mobs together it makes it worth. Always play flame patch and use searing touch on below 30% adds to get hot streaks for faster flame patches
