i voted for the [i]"Maybe, if the new creature fulfills some requirements"[/i] and [i]"A common creature (anyone can recruit it given that the requirements are met) - new abilities,auras"[/i]
since not all players (including myself) can get a hold on any of those uber-rare crits, why not have a creature that is "not that hard" to get, but, yes, has drawbacks obviously, like pain-in-the-b*++ requirements to make it advance to its next level(s).
at my current mp level, i am still sticking with the old-school crits because i have not yet done any quest that will unlock me to other bestiary farm. yes, really my fault, i'm not that good at solving quests, that's why. i know my reasons are unacceptable, but since most players are hmm, stronger than i, maybe that "new creature" can give me (or, some of us) the FIRESTARTER that every newbies are looking for.. well, just my opinion hehe
