If you want a mercenary, pay another player some gold and pretend.
Mercenaries work fine for single player RPG's, but in a game with lots of other players, why not just do things with them?
considering this is an MMO and there are actual players to group up with, an NPC follower is unnecessary.
@Suntzu1414, @ItsRejectz, @Forestd16b14_ESO Those were Cyrodiil Merchants to guard keeps. COMPLETELY different from what is being suggested.
All it will do is encourage even more solo play....
