Hey there! My guild on Hyjal - Horde is recruiting some more for our raid team. Raid days/times are fri/sat 6-9 (pst) we do M+ thro out the week and other shenanigans as well. We are a heroic focused raiding guild that strives for AotC and we also dabble in mythics but nothing too serious 
Laid back, fun loving and usually always someone in discord. We are looking for more active and quality players to fill our roster for current and future content.We also have a tanking position open if your brother is wanting to stick to that role. If you are interested please add me to btag and we can chat some more :). My btag is Hera#1937
You can also check us out on our forum post and drop a reply there if interested. The Forbidden Rising is recruiting! (8/8H TEP)
Cheers and Good luck!
