I think you should go for dusi cause it’s very good supporter as well as good sweeper, and it’s shield field gives massive impact in most of the battels (both pvp and pve). I know flocc is also a very good monster but imo if I don’t have dusi i’ll definatley go for it. But in the end it’s your choice which one you choosed based on your team building strategies, because now both dusi and flocc became shop only monster. So GL!
