Does a fungi "fix" Barb shamans?

[E-Queue]

I know shaman race questions come up like twice a week, but I didn't find this exact question answered anywhere. Apologies anyway for an annoying topic.

I'm considering rolling up a new shaman for some casual fun (mostly solo, limited grouping, definitely no raids). Everyone agrees Barbarians are the worst shaman race, but I just prefer their fashion over the other possible races. I don't wanna gimp myself by rolling the worst race for the class, but it seems the main Barbarian downside is just the lack of regen. Other than that, they're no worse stat-wise than Trolls/Iksar. So... my question to any shaman vets out there is if I am able to twink the toon with a fungi, does that pretty much completely negate the Barbarian gimpy-ness? Or am I still going to regret not being able to stack fungi regen with racial regen?
