Hello Sanavi, and welcome back to WoW!
D’vali is on the Alliance side, Dalaran server and we are seeking more awesome people to join us for, well…everything! Our raid times are indeed on Sat and Sun from 10am-1pm EST but can be shifted either forward or back a bit depending upon our raid force.
I am going to leave our recruitment post here and you can browse through it and see if we might be a good fit.
