Hi Yigui,
I feel your pain we too have been looking for the past month or so and it very much is difficult out there. Our guild Bloody Sundae (H) - details and contact info below - is looking for more to fill out our team. We already do some collab with others we have found in a similar boat i.e. don’t want to leave their guild, but still commit to raiding with us. So i’d say we are definitely open to chat! Our Focus is usually mid-level m+ and trying to get AOTC (M+ usually between 2-2.5k). If you are interested in chatting reply here or contact me at my battle tag Storm#1965
If i don’t hear from you, I wish you luck on your hunt!
