Just saw your post as we are looking for another dedicated healer to complete our 10 man team for Nighthold HC. We are a semi hardcore casual guild with no current plans to push Mythic, but we have a solid core group just missing a healer. We would be more than happy to have you join us on discord for a normal or whatever if you still need a guild. We have always gotten curve before the next tier of content, so if you are happy with progressing through HC with us that would be amazing.
If you need to get hold of me quickly feel free to add me on bnet GladiusMax#1231
