Unplayable at high levels and bug filled
The lag from the new AI results in creatures being able to attack you long before you can even target them.
The only way to gain XP at high levels is to endlessly redo repeatable quests.
The quest engine is great but only takes a new player to lvl 30.
The new game has completely removed the open ended and versitile profession skill trees and dumbed the game down to the "iconic" professions. Ranged professions are the only viable ones at this point.
With the removal of decay crafting has been gutted.
