Right now, the customization system is very good. I like the fact that customization affects the look and stats of your character. Having stats help customize your fighting style. And there are a lot of options for cosmetics

I'd like it if you could rework the gear upgrade system. Right now, there is only a very small bonus of 1 stat. If there could be a bigger bonus and you could choose which stats it affects, you could get a very custom game style. Another idea that would be new players friendly is no upgrades. You simply find a blade with +2 damage and +1 stamina. That way, high level players would have +4 damage, +3 stamina and +4 defence blades, and you still have a bonus significant enough to customize your game style.
