To your first issue:
Perhaps it is a bug, perhaps it is just the crane, but remember, we just had an expansion come out, so be patient and hope the Devs can fix your....'small' problem. ^_-
About your PS:
Raiding, dungeoning, or questing hunters need only 5 pets to be able to operate efficiently: A tank pet, two dps pets, one having the agil/str buff, and one having the 5% crit increase buff, a cunning pet for utility, and a spirit beast if the hunter is BM.
Do not think that we have too few slots, instead think: "What pets to I enjoy? What pets do I want to show to friends, the stories I can tell about them?" And then fill your stable with those pets. I have a collection of sabers, because I enjoy how they look. I know by heart where each one came from, if not exactly the spot where I tamed them.
The pets I have with me when I go into the world are my 'utility' pets, and the ones in my stable are my 'showcase' pets. On occasion I swap sabers for a change of pace, but all in all, I don't go out and tame all the rares/new species just to say "Yeah, look at my fancy new (new pet)!"
Don't get me wrong, I also strive for good looking 'utility' pets as well. I camped for Loque'Nahak for weeks, I fished the lava pools for a month for that FLAMING turtle, Terrorpene, the dog I rescued from Kara was fun to find for arena, and the hellboar I tamed simply because my favorite color is green, and he was also my tank for 62 through to 80.
Small pets can be a bit disappointing to show off, but always remember, they're your pet. When I am able to go hunting for the one new rare I want, that's all I will be aiming for. No cranes for me, thank you XD
