-Better customization, not only for humans but for demons too
-If you will put Slayer mark on the slayers then make the demons can use a "transformations" too. A example of this is Rui, he starts using blood to make his strings stronger, Douma can create ice particles in area making slayers take longer to breathe and increasing Demons cd, Akaza can use that pattern and giving him some chances to Dodge atacks, Arrow could control the arrows giving a little auto aim (Still able to dodge), Explotion get a key to explode who maked him damage. I think you guys alr get the point. (This is only if Demon slayers get Slayer mark, so demons can have something cool too)
-If you are going to put the hunger system back in this version, make it less annoying for slayers or put more places to buy food, it really is very annoying to have to walk a lot just to be able to regen, it's really time losing.
-Depending of the map length, there should be a traveling system. (Also, nice oportunity to make a reference to the mugen train).
-Please don't implement any family or name system, they are really abused alr, it adds luck based and ptw.
-A way to reset breathing/blood demon art less annoying, losing level isn't effective, it maked everyone to just wait for c0d3s, instead there could be a hard mission wich could depend of what breathing/bda you got. This would result in maxed people actually playing the game to get what they want instead of waiting for c0d3s.
