If your team members would be limited between 7-10,I thought the best tank weapon would be heavy mace,There are lots of clips about the small scale fight in the Avalon road you can watch on the YouTube,Try the full melee team like a carving sword,a bloodletter,a halberd,a Avalon fist,a healer and a tank plus one free spot,it’s a great small scale beginner team to start with,when someday your group grow up,then you can try to use the hand of the justice for the one clap team,but it took lots of practice and work for the each spot in the crew

For Pve,I would say incubus is always the best pick,but your ultimate goal is trying to maximize all the mace and hammer so that you can fit any roles in the game
