Hello! I am not sure if you are interested in changing faction or not, but if so my guild Evolved might be a good fit for you! We are an 18+ community and most of our members have families, jobs, etc so we understand the importance of real life coming first. Because of this, we do not require 100% raid attendance. We run 2 raid groups, so plenty of room for you! Everyone is super friendly, mature, and a ton of fun to be around. 
We like to focus on having a strong community as it makes the game so much more enjoyable! We do all kinds of things besides raiding such as M+, arena, world pvp, dungeons, etc. We just like having fun together
We raid Tues/Fri/Sat from 9-11 pm EST with an optional hour on Fri/Saturday. Evolved is an Alliance guild on the Proudmoore server. We work really hard to make sure everyone that wants to tank gets rotated in. We may not have room for you to be a full time tank, but definitely will make sure you get your fair share of tanking!

I wish you luck in the guild hunt! Finding the right group makes a huge difference!
