I was a multi glad (season 8 and 9) and RBG Glad (seasons 9 / 10 / 11) and ended season 10 in the top 50 in the world for RBG rating (2754). In Vanilla I was a hardcore raider (Hunter and Warrior) and full cleared MC, BWL, Ony, ZG, AQ20, AQ40 (no C'thun, Ouru, Visc), Naxx full clear Arachnid, Noth, Instructor, Gothik. As for world bosses I killed Azuregos, Kruul, Ysondre, and Lethon.
I raided from vanilla through cata but most of that isn't to relevant for the most part. Things of worth would be 10m heroic Lich King pre Cata talent tree's, Sunwell up to Muru, and 10m heroic deathwing pre panda talents.
I'm just wondering if theres any guilds that are recruiting and what classes they are recruiting before I waste my time leveling a character that I wont be able to do end game content on due to lack of need.
