It doesnt. I will say quit if that is what I mean. I gave ESO as a prime example of other MMOs with just a few “buttons”. You cannot name another MMO remotely as popular as WoW that does not have “ermahgerd too many buttons”.
Its basically WoW and FFXIV that are kings of the MMORPG market with games like ESO and GW/GW2 way the hell down near the bottom. There is why skills are important, combat good enough to retain a lot of players.
