Been playing hardcore (as in if I die, it's game over) on vanilla WoW. Kinda crazy how mobs that I wouldn't even give a second thought at mowing them down with my spells and abilities are now terrifying. I used to just facetank the troggs, quilboar, etc. but now I have to think of the fights I take more of then than I did in the past. For instance, Razormane Hunters and their wolf pets patrolling into my area have made me bail from fights, I avoid most caves so respawned mobs don't jump me, etc. It's super fun in the end but sometimes nerve-wracking when you're about to lose hours upon hours of progress from a stupid mistake you made.
