Pretext: OSRS player thru and thru, it's my main game. FFXIV was my side game up until Dawntrail (which is obviously way more comparable to WoW). Have much more experience with FFXIV in the late game with raids, which my experience with comparable content in WoW is much more limited. I have tried retail WoW plenty of times and I love how large the world is, the (old) lore was so awesome, classes/combat feels good and fluid to play, and I've put a lot of hours into WoW getting numerous classes to max level, but...
When I go into dungeons/boss encounters in WoW, it just doesn't feel gratifying to me. I am aware that people complain about the GCD of FFXIV, which is fair--it is much slower pace
