*sighs* time to squish some rumor's...
1. all pets have the same AL.
2. all pets have the same health, depending on their 'evolution". but on the same "evolution" every pet has the same health.. whether it's a Bear or a Moa Bird
3. all pets attack at approx the same attack speed, again depending on the "evolution" it is going on.

Do note that the AL's listed will now be incorrect as ANet have increased the max AL to 80, up from 60.
