I've encountered this issue soloing on a lot of pet jobs... people kill shotting a monster my pet has for the easy xp... happened a lot on bst pup and smn, i wanted to rip their heads off. Its not completely a dynamis issue but something to do with how pets work... if the pet can kill the last 10% while you're pulling another monster to it or w/e both the pulled and the engaged should be claimed... Although it seems like the people who are arguing against the point have not had someone steal a kill while they were on a pet job...
