We don’t use add-ons in FF14 because we don’t need them in FF14. FF14 is easier than WoW by orders of magnitude. Sorry, but it’s true. FF14 excels in story-telling, the crafting and gathering system, the glamours system and the social aspect – all things that WoW is woefully lacking. But FF14’s combat difficulty is nowhere close to where WoW is at.
It sounds like you like to be challenged. Get some raid logs in on Heroic raids here in WoW and then apply for some Mythic raid guilds!
