Shitty PC optimisation, world is too static, game comprises of massive grindfests with short story quests in between which is mainly characters doing emotes followed by text, lack of things to do other than grind, crafting is boring - I even stopped macroing with my keyboard because it's just that boring, music is a bit disappointing knowing that it's from Nobuo, classes are badly outlined, enmity system is broken, repetitive battle animations, gladiators getting weapons that look unappealing under rank 30, macros needed to change classes/skills, game gives little motivation to keep playing, no post-character appearance modifying because my character looks worse than expected after character creation, market wards instead of auction house, UI is consolised - no drag and drop, selling items and transferring items to retainers takes ages, repetitive landscapes, game story converges in Ul'dah at R20, player population centered in Ul'dah, leves always at same location, lack of variety in leves, 8 battle/crafting leve limit, stat allocation makes little to no difference, lack of mob variety, UI elements are too large (I play on 1440x900), large rank gaps destroys SP - I can't play with people of lower rank - macros needed to change items/skills for class change discourages largely.

Those are just things I listed off the top of my head.

Off topic, I bought the CE and got a cheap cup I can't even drink out of.
