Hi there.
If you are interested on playing the warlock as Alliance, I run a guild on Quel’thalas which focuses on Hc raiding and regular M+. As we are on your connected realm a transfer wouldn’t be necessary. We are 7/8HC atm with Azshara likely to go down this week.
I’ve left our link with more info below and please feel free to add me for a chat on Bnet Dodger#2127 or Discord Maxi#0222. If not then best of luck with your search 
Max.
