Well to break your points down:
How do you know they won't let you keep your gear? Even if Warsong players earnt their gear differently to Nelth players, you still earnt it and it should not be taken away.
I have 0 interest in gold farming or any of that crap. I log in, afk till there is queues happening, do some games then afk/log off. Not once do I bother to go farming and I have 7 full geared and full enchanted and gemmed toons.
Yes because SoloQ is totally going to happen, Kappa. Theres more outdoor PvP on nelth than Wsg. Have you not seen all the posts on the forums involving Gurubashi Arena/ Tol Barad / Uldum wars between alli and horde?
There is a better chance to get a bugless core if they only had one core to work on, yet if they ever did add AT core then that means workign with two. Different fixes, double the total bugs for Warmane to fix.
Voting for months straight for one piece of transmog gear without wanting to blow your brains out, is the biggest challenge around imo.
Yap because you totally have CD reset and Free faction change at the minute.
I honestly believe you should get the whole AT core idea out of your head. One of two things will happen, Either they just never get round to it for whatever reasons or they add it in over a year+ which by then there would be like 20 of you on Wsg. I thought it was meant to be PvP addicts on Wsg that would do anything for faster queues in 3's...even if it meant some workarounds, but I mainly see Nelth players trying to do that...
