The reasons you "hate" the possible changes so much are so insanely stupid I actually can not even start discussing them.

You act like WoW is the only other MMORPG out there. SE is not copying WoW.

Every single MMORPG has crow control, some kind of auction house system, PvP, player housing, add-ons and multiple mounts.

Even FFXI had add-ons, those were maybe not official, but they were there.
