Looking for mythic raiding capable grp

Looking for a group that either raids weekends, or early weekdays willing to do Mythic raiding progression semi casual not overly aggressive, sarcasm and veteran humor appreciated. I do heroic with a RL friends and family group Tue and Wensday evening PST. But they are small #s unable to run mythic raiding anymore, some are eh but friends. But I’m not wanting to leave guild.
Used to be in top 10 global back in the day, took more casual to top 100. Global 1 in other MMOs. Now I just do baisic Heroic raid and mythic pluss. Since I’m a veteran and my health isnt great. Been blown up, irradiated, etc.
Currently was playing a DH 636ilvl M+2636 but they are in a trash spot right now. So re-rolling to marksman hunter 631ilvl and M+ 2638 for end of this season and season 2, figured I play him for pvp anyway. Maybe more people willing to do some mythic pluss grps.
I have good days and bad days medically, and work with a veterans charity association. I really care less if one sides more Horde or Alliance all my alts combined from when I used to raid hardcore is 33, 70-80s. I typically linger in LFG and pick up pugs but want something more regular.
