Viability of Protadins in cataclysm?

[zenga]

Recently I started to play my pally solo in bg's, prot spec with mix of ret (crit/str) & healing (sp/crit) gear. I'm far from where I wanna be gear wise, but despite that I'm having a blast. Some time ago i started with a warrior + 4 pally team that i shelved after trying out retribution a couple of times (solo). Playing the retribution spec is just not my thing, can't say I like it. Melee wise I'll hook this prot pally up with 3x dk + priest soon.

Long story short: I was wondering if anyone has an idea about the viability of protadins in cata. From the brief look I had at the talents i'd say yes. I have a lot of leveling to do on the team and the sole purpose would be to run multiple protadins at once. Thus wanna more or less hear other opinions before i take the jump.

edit: forgot to add my focus is bg's, not arena
