I love the idea of a class hall, I love mine (The maelstrom) but the upgrades and quests being mission boards are really irritating me already.
I started out with having to find thunderfury and meeting Thunderaaan, and this was amazing. The next steps were to do four 8-16 hour missions to kill Thunderaan's enemies, which I sucked up expecting there to be something cool again afterwards, instead Now I'm sending a random follower on a diplomatic mission to Therazane.

Really disliking that things I could do as a player (I sent a 103 follower and a couple minions to kill them ffs) are being given to NPCs and the mission board
