The same Renowned Pixie has been sitting in the Abyss on Atlantic all day. The spawn with the fairy dragons has been sitting at level 3 all day. Same with a few others. People farm imbuing materials and just leave when the boss pops, because nobody is that interested in a 1% chance at an artifact worth like 200k. Yeah I can grind through the last of the previous spawn before farming my own imbuing mateirals, but the boss is supposed to be the culmination of a spawn. Not a big worthless lump you leave sitting there for the next sucker to waste their time on. Make the bosses drop imbuing materials, or just have them despawn if no one kills them, or something. I dunno. When the boss is just some pile of crap speedbump that you abandon, SOMETHING isn't tuned right.
