Playing on PC with KB/M and just a thing I would personally like is a way to have Heavy Attack also be able to be able to be remapped by pressing multiple inputs together, like some other games do (Horizon Zero Dawn, Assassin's Creed Origins + Odyssey). Instead of only having single individual inputs (which are still great to have as a choice). That way you can share a button with another action, without them having conflict. Sort of like how the Range Attack works in the game already, where it shares Left Mouse with Light Attack but only used when holding the aim button.

The games I mentioned above use an input of both of Left Shift + Left Mouse for their Heavy Attacks. I've gotten so used to this in various PC games now and find it very comfortable. It would be icing on the cake for the controls for me personally. Not sure if it'll interfere with the game though, such as if there are sprinting attacks (and you do not use toggle) yet want Shift to be Sprint and also Shift+Left Click to be Heavy Attacks.

Thanks!
