We are due for one last major update so now is the time to make them I'll start with what I'd want.
Flurry needs a rework, as the swords main skill it's very inconsistent with a 15% chance to miss. It should only take the first hit into account. They are like firearm pistols prebuff good weapons, but too much room for error.
More unique serpentborn gear, at least for the bosses. Magnar a riot armor set and sword, Oyensorm a thought control robe, Baenkraster a bone armor set like metal armor, Eldran a metathermics armor set.
Also it would have the benefit of making the bosses harder.
