I agree, but I would take it a step further. The left click attacks feel boring, weak and clunky to use (without holding shift). And to my experience I have not made a build yet that use them a lot, I've either balanced willpower/rage usage or had so much rage gain I can pretty much spam forever. I have not tried a staff (pure willpower) build yet, so don't know for that.
I would prefer to be able to put another active skill there but I am pretty sure that will not happen. However, what I do suggest is adding skill modifiers to these attacks. These modifiers don't have to be too exciting, I just simply find left click super boring in it's current state. This way players can customize them a bit more to personal preference, as well as them feeling more impactful. I think the targeting issue is also a big down

hi, just making another comment hoping wolcen ad's attack without moving option for left click, left shift mechanic is annoying and dodging is difficult.
I have hope that wolcen will add this feature soon.
