So I am currently level 48 storm, i completed every single side quest up to mooshu, i just did all of grizzleheim and am currently working on the wintertusk side quests. I havent started mooshu yet and everyone is telling me to. opinions??
You... are going to be incredibly overpowered when starting Mooshu, I'm honestly impressed, lol.
You'll be perfectly fine. Most people start Mooshu around level 30. I'm a little over halfway through on my balance wizard and I'm level 41, and even that's higher than many people's because I do side quests. You'll probably breeze through the world no problem.

By the end of wintertusk you'll likely be level 51-52 if you just started. If it gets frustrating like it did for me, by all means go back to MooShu, content's much easier there.
Mooshu is generally for high level 30s - 40s. You're overachieving in that area with that level (which is a good thing for DS and so on). Keep on doing what you're doing.
