In solo situations, it's definitely bad when PoM-Pyro is not up. However, in BGs you're mostly fighting in group, and with proper positioning you might be able to get off a couple of fireballs here and there. I think PoM-Pyro provides great utility in WSG. Not so much in AB when you're defending a flag alone, you get sapped and don't have ice block, but it's still nice to burst down healers.
Then again, as you said, fun > everything else, and there's no denying that, even with crappy gear, one shotting people every 3 minutes is exciting.

As I said in another post, it's not that it's the only viable option, but you can put equally geared mages with opposite specs, and the frost mage will always do more damage than the fire one. Just for obvious reasons, MC and BWL mobs and bosses mitigate fire damage. Of course you can go as fire, but don't expect to top the damage meters in any fight, which should be the main goal of a mage in end game raiding.
