Spriest is winnable, but you need to be very reactive. Spellsteals are important and kiting is too. (what, kiting a priest?) yes. Don’t let them use fear on you, kite them and keep em slowed. Being dispelled is just the name of the game; ignore dispells act like they dont exist and anytime they’re dispelling you should be hardcasting. You should also hardcast during heals, and don’t drop your abar either, keep ab’s going if you can, only use abar if they’re silenced and you think it might score a kill. Every pw:s should be yours instantly.
War is weird now in df, idk why. My tactic is to string alter/blink together on the very first charge, then alter-back after 2nd charge, and blink out the 3rd. You have a 4th blink if you spec displace. If you don’t do the alter at the start, you’re getting caught. Ice nova, coc, firebreath and blastwave will all help you here, but do not miss any of them and be calm the whole fight. You don’t need to poly a war, but you want to fake a poly to get reflect out the way early, first chance you get. Slipstream is vital; if you don’t have slipstream, use what you’re good at to keep dmg going.
DH is a kite battle just like war, but roots are going to be massively more impactful. You actually DO want to get sheeps off against a dh, but you need to only go for it, when you know for certain it’ll land, so be patient and wait for your sheep window. You also want to do at least 2 sheeps, let your cd’s fulfill again as much as possible, and then even tho you may not like it, you’ll have to string something like icenova or frostnova into your burst rotation, becuase they’re just too quick. Mirror images are magical in kiting a DH, however the timing is important because if they’re bursting, they’re going to hit you 3 times and kill your images nomatter how far away you are, so wait until you notice their dps significantly drop, then use images.
DK, you’re dead. There’s no hope for you. There are other arcane mages on these forums who are master elites; and hopefully they know how to beat a dk. Me? I’m not that good. I do however notice that despite their snare resistance, roots are very effective. I have freezingcold root, icenova, frostnova and combined with the alter combo (above, with wars) and displacement, I can avoid dk’s ONCE IN A WHILE. I had a really powerful arcane mage friend who would lure out their silence and then just stand still like a target dummy and hardcast em and he would win, but he was a league beyond me, idk.
