I feel like boss gear is stale. Best in slot, but honestly asides from getting that "gear score" up it's not wildly better than Green or Blue tier. So my idea would be individual bosses get sets. Dim Tree, Muskans, Griffons, Urugons, Red Nose, Bheg's, with each set focusing on different stats like AP, DR, Eva, HP, but all pieces should have similar DP cause gear scores are such an important thing to people. Obviously none of these ideas below would be an absolute must but just throwing out some ideas.

Dim Tree set and pieces can focus on health and health regeneration. You're a plant man, get that sunlight and grow buddy. Set bonus can be bonus health regen based off missing health %.

Urugon's can be DR focused. Set bonus can be sacrifices all evasion for even more DR. DR has always been a disappointment.

Muskan's AP. The Monk's set can focus around having average DR and EVA, nothing special, but an AP boss set. Cmon. Set bonus can be bonus attack speeds/crit with lower health

Griffon's Evasion. I feel like big bird jumps around a lot, and feathers, and yeah. Feels more evasiony to me. Since EVA accessories have less or no AP on them the set bonus could be successful dodges give a damage buff for the next 2 seconds and can stack up. So the more you're being attacked and dodging the more damage output you have but quickly disappears out of combat.

Bheg's accuracy. He spins it right round right round baby. Like Muskans, just average DR and EVA but hidden accuracy. Set bonus can be accuracy related. The more you attack a single target the more accurate you become. So a Bheg vs Griffon fight would look like Griffon's  EVA is stronger earlier in the fight cause it's buffs to damage with dodges but if Bheg's guy drags it out accuracy isn't a problem anymore and he can pull ahead.

Red Nose's current buff of HP regen might as well not exist. Garbage. Maybe Red Nose can be a CC resist set or even a noob gear set of average stats but bonus EXP/weight/etc. An Alt armor set when you're leveling new characters. OR, a very average set but more slots for crystals. Maybe 3 or 4. Set bonus could be to extend buff/scroll/food durations 50%.

They need to make DR scale more than 310 which is the soft cap. Not everyone can use evasion especially early on right now.

Thank you so much for the suggestion! I have added it to our daily suggestion report. ??
