I kind of have the same question about wolves too. Cyrodiilian wolves seem to be solitary creatures that don't move in packs. One wolf attacking a fully armored human is a bit silly. And then they have the nerve to fight to the bitter end. Are they insane, possessed wolves? Stupid wolves? Depressed wolves that want to end it all? Maybe I'm looking too much into this...
So yeah, give me your theories on why mudcrabs are so damn unfriendly .
