Sounds like Wow isn't for you.
You've moved on. We're happy for you.
Meanwhile we'll just do out thing. LFR here, quest there, grind this grind that. Play AH. Play pets. Jam and chat with friends. Chase 'chieves and maybe that Workd Event. New expansion soon. Dig around the lore. Proving grounds or Brawlers for the kicks.
Then there's PvP if any of that gets boring.
Oh you're only into exciting PvE then go Flex, aspire, go Normal. Grab or make friends as you go and join OpenRaid for some new challenges. The point is, there's loads of things you can chase in Wow a great deal of which is raiding. It sounds like you're bored of that so really you're bored of WoW. Which is cool. Take a break. Come back later.
