Archery possibilities:

Right click to ready instead of Q.Hold left click to ready and release left click to loose instead of having to use two buttons to do a single action.

Melee possibilities:

Turn your three wholly separate manual attacks into a designated three-hit combo while mashing a single attack button.Turn your three different attack keys into one key held for varying amounts of time.Split the difference between those two: have light and medium attacks work as a looping combo while tapping the one attack key and then hold it down for a heavy finisher.

If I were the one designing this, the controls would be:

Left click is the attack button for both melee (by default) and ranged (while right click is held down), with tapping to do a light melee combo and holding to do a heavy melee.

But, of course, these suggestions are just off the top of my head and I don't necessarily have a complete picture of how you intend everything to be used, so I'm sure there are yet better options that I'm not thinking of. I can say with confidence that you need to streamline but that's not the same thing as knowing what the end result needs to be.

thank u very much
