I’m desperate for some new armor sets; there are just too few! Also, I know that there has been some clipping issues with the cloaks, but fixing it would not only add a brand new look to your character, but would also improve the current cloth on armor sets. For example: the heavy Arah set would look great with some shredded cloth blowing in the wind, or any medium armor with a realistic looking coat. Cloth has a static feeling in my opinion, and fixing it would be such an improvement!
I’m also a huge fan of spears, but unfortunately they are only for aquatic combat. Therefore I’d suggest adding polearms as a brand new weapon type. Maybe adding 1h flails would also look great, or crossbows as a new ranged weapon.
These are just some ideas, but still the most important thing for me is adding more armor sets.
