So right now we are kinda on the opposite extreme of 100% drop rate, the items are really hard to obtain now. I like it like this BUT there could be some changes to help the dungeon's playability.
1.) When you kill a boss, its kinda un-fufilling because you get like all whites, yellows and greens as drops. Maybe make it impossible to get these kind of items on a boss, but still keep drop rates the same.
2.) It is very expensive running the dungeon. I know you guys already bumped up the gold drop rates, so heres what I suggest. Add some rare drops to the boss that are not as rare as the shadow gear. Like maybe have the witch have a small chance to drop a laser wand. Or have the archer have a small chance to drop a sunblessed bow. This way people still get something to fund their dungeoneering and get the fufillment of a drop.
Like this, except you wouldn't need lucky elixir's and Lones strangely *cough* high luck .
