i played against 55 bosses so far and completed 2 runs with paladin and rogue. both were really easy compared to, say, hunter. couldn't find a way to defeat any of the 5 last bosses witht hat class. any advice is welcome btw.
also tried druid and seems like buff - zerg is a viable tactic.
priest seems doable. tons of resurrect options but if you face that trogg boss, it is %100 gg.
mage, geez. almost completed that run too but the evolve boss turned his silenced (he silenced it himself btw, silly) 1 or 2 cost minion into https://hearthstone.gamepedia.com/Nerubian_Unraveler . you can imagine my face hehe. i had a flamestrike in hand but RNG is RNG i guess.
back to the title. how're you doing so far ?
