i'm concerned about murkablo's self-esteem levels once he realizes that he's not going to be the top fiery vanity pet. it's obvious he was trained by the same person that trained deathy, and while that's probably cost-effective and efficient... it's a bit of a let down.
don't get me wrong, i enjoy deathy's fire-breathing, smoke-ring-burping ways, but i enjoy them when deathy is doing them. murkablo, on the other hand, deserves to have his own unique animations imho.
not to mention i can't imagine deathy being too pleased that another companion is downright copying him and stealing his
i admit i haven't played the previous diablo games, so i'm no expert on diablo and his abilities, but i've talked to some friends who played the game before and i found out that the boss has a pretty neat fire shockwave type ability. after watching some youtube videos on the diablo boss fight, there seem to be a few unique animations that murkablo could pick up and learn. but yes, one of them is still a fire breath that's the same as deathy's fire breath, so it doesn't seem like that one is avoidable. some other ideas for murkablo: he could interact with other diablo-themed pets, summoning a hellfire, etc.
regardless if murkablo gets to have his own new set of animations or not, i'm still excited to add him to my collection. i know it's not blizzard's top priority to make each non-combat pet extra unique and special, and it probably takes a lot of energy and time away from other projects to change/update companions. would it be a nice treat if murkablo learns a new set of tricks? definitely. but it's not the end of my world if he continues to live in deathy's shadow (let's face it.. deathy knew all these fiery animations first, while murkablo's just a copycat :P).
