Oh ya, another good hunter trick I picked up recently, that's obvious in retrospect but didn't occur to me. Use a freezing trap when taming pets. You don't have to take a beating as long if you can keep the potential pet nicely away from you.
I tamed a black bear in Loch Modan at 10 when I got the skill and have stayed with him pretty well exclusively. I tried a swamp jaguar for a bit but with the pet speed bug, his much higher pursuit speed was pretty well useless most of the time, and he didn't seem to tank as well as the bear. I've tried a turtle but the supposed better armor class wasn't there when I compared him with my bear so I went back to the bear.
Yes, freezing traps are almost a necessity when taming, especially some of the nastier stuff later on (heck, taming the King is kinda tricky in itself if solo).
I haven't found the differentiation between 'non-special' pets (no resistances, run buffs, no fast atk speed, etc) to be anything at all really. While I haven't done scientific analysis of it, using several different kinds of pets never really favored any type over another noticeably. So I'm still sticking with my Longtooth runner. The run speed bug is annoying, but there are a few workarounds that make it less annoying than it could have been.
Various pets for various situations. This pet has good resists, this one is fast. That one has a lot of hp or damage mitigation, but the other is a glass cannon (high damage but fragile). In essence, create a microcosm of the (well-done in WoW) class differentiation but in the pet world.
Well, exactly. And to an extent, it's the system that's in place and being patched out, which is why I'm pissed about it. I /like/ planning ahead, if I'm going to the Searing Gorge, I'm going to bring Mortimer, my roc from Tanaris with 250 fire resist (yeah, I went and got him, he matches my badass red jeans (tm themexicanrooster). Even so, he doesn't resist much more than my 0 fire resist Longtooth.
Still thinking about a tank pet, but hate giving up run speed and/or attack speed.
