Do you still like WoW's system otherwise and just want the same thing without the flaws, or do you truly want to try something as different as possible? ESO is a very different game from WoW. Even though it is not exotic like EVE or SWG, many of its design choices felt like it was meant to be different from WoW "just because they can". They can be refreshing to many while also frustrating to others. Instead of 3-4 hotbars of skills, you always run with 5 active buttons at a time. Instead of target locking, everything is either manually aimed or auto-targeted. Instead of "every role matters in a dungeon", the dungeons are very carry-friendly and fluid role-friendly. Instead of everything designed to be anti-kiting, kiting is everywhere from normal mobs to bosses to pvp... It might be great if you are looking for a break from the old mechanics, or it can be awful if you still appreciate the classical MMO formula and just want something familiar but different.
