Imo Khadgar was a much needed key figure after WOTLK expansion

Up till the lich king, we had our main storylines. With cataclysm and beyond, blizzard introduced some new lore but without a real direction and follow ups. I like khadgar, despite being made a meme, because he shows us a direction. And along him we get to do side stories, be it the orcish clans, draenei in WoD or illidan and maiev in Legion.I like him being goofy at times, serious when needed and annoying during quests. I hope he can stay as long as blizz finds a replacement.Also better than green jesus
