ffxiv 1.0 i was able to play duing EA into launch all the menus slow and stuff. ARR cant even login or do class quest i get stuck in a loading screen.
age of conan was broken but i was still able to play that one and that was enough to kill that game.

but by now they should have an idea how to make a mmo work been 11 years since there first mmo. the game has nothing new and should be expected to work.
but in this day and age people are alright buying games that need patches & DLC to work right. now that lazyness is biting the dev they frogot how to QA the stuff.
