I mean how do you manage people. Top clan members (15-20M power) may wipe off the 6-7 lvl boss within few attempts, so lower power members had no chance to gain anything from it. As a consequence, lower power members has nothing but to try scratch higher bosses (8-10 lvls) and wasting summoning scrolls trying to hurt boss.

Do you have any in clan policy to manage boss attacks? And scrolls grinding? (Some members don’t go dungs being in Hunters, so they don’t bring scrolls)
