Interesting bug, hunter pet, lust

Just thought I'd share as a PSA, but I think it's a bit of a bug. I play a hunter and I've been switching between MM and BM a lot, depending on what dungeon/raid I'm doing, how I feel, etc. I was traditionally a BM only hunter but switched to MM this xpac because of BM sucking so much without the 4 piece bonus and Raz bow (which I did not have at the time). I've since got it, but anyway.

So I queue for this 17 Ruby Life Pool, putting "lust" in my comment as usual. I'm MM at that time, MM works really well in RLP for the burst AoE on the first boss.

So we get to first boss, we start the encounter and I call my trusty spider for the lust as we're pulling and I get a message.. pet is dead. Woops, it died in my last run and I didn't revive it. No biggie, I proceed to revive and get a message.. In all the action I don't see what it is, but I fail for a whole 20 seconds trying to revive/call while the group is yelling at me to lust.

After the fight I found the issue. The pet that I had when it died was exotic.. and switching to MM prevents me from having exotic beasts.. so my pet is dead and cannot be revived. We're deep enough that going back out the instance to respec is not worth it, so we did the whole instance without lust and me being called a huntard for not having lust.

I'm not sure if it's a bug or a feature, but I had not foreseen that happening and it's pretty sad that there were no fixes that I could do inside the dungeon.
