I agree pets level so much faster now , level 20 hunter with a level 15 pet around 30 minutes max to get pet to 20 , at 40 with a 35 pet well less than an hours play and my 70 saw her 65 pet hit 70 in around 2 hours , farming sure rules to level pets .
I also find apart from a very slight loss in damage a pet 5 levels below makes no real difference anyway , they survive and hold agro just as if they were the same level , and it is giving me the chance to try all the pets for a few levels just to see which i prefer now.
so far Wasps are my favourite apart from my cats which i shall always have but i have not got around to the Silithids yet and they might just be the pet for me.
