Maybe we find Leviathans so satisfying to fight because they have so many breakables? Take Lagiacrus; cut the tail, smash the head, break the back spines, scar each individual leg. And there's an almost 'popping bubble-wrap' kind of fun to breaking each piece of Agnaktor's armor.

Compare this to, say, Brute Wyverns, also introduced at the same time; cut the tail, break the head/scar the jaw... and that's kinda it. Not that Brutes aren't good monsters as well, though.
