For me:
1) Taxes in a video game. Just no, I'm not farming for 1 hour much less 12 just to pay for a house I bought (which they steer you to the most expensive because 1st hit is half off!!)
2) Unpunished dupe and exploits in a PvP game
3) STUPID high instant travel costs, and another tax the more you carry. I'm in Blue Protocol now (yeah yeah lol) and having fun, because I can instant travel with no cooldown for FREE, and even in goddamn combat. Feels good
4) You needed to farm rarish items to put together a disposable dungeon key just for the privilege of running a dungeon? lol. People screamed about this, but it took them too long to change this.
I did love the visuals, SOUNDS, and even the bits of lore spread around.
