You know, although I first thought that elephant-morphs are silly as hell, the idea of a mammoth-morph is pretty cool. Just grab a spear and start hunting sabertooth-people as vengeance for the ancestors.
Too slow. Sabres would outpace, outmaneuver, and outrun a mammoth any day. Even throwing a spear or using a bow is futile with what will probably be stubby non-dexterous hands.
They'd be better off using their strengths to their advantage. They're large, powerful, and hard to knock over. I wouldn't find it hard to believe an elephant-morph warrior using two shields in each arm while using the trunk as their weapon appendage because the shields can be used to block attacks that would whittle them down or otherwise knock them over while the trunk can snake around the shields to stab or slice at whatever is attacking while also being somewhat armored itself.
Not to mention they'd have no need to hunt, being herbivorous and all. Revenge would motivate a killing spree I suppose but from what we currently see in elephants they don't attack unless they feel threatened or want to protect something so mammoths were likely similar.
