I agree with that laser weapons should not has a recoil, at least “noticeably”.
And for people that worrying about its “feeling”, “impact”. How about just make the screen vibrates or gets blur then? I think that would be reasonable or acceptable enough, I guess.
And one more, I used the Beam Staff a lot; its beam has no recoil, the weapon it self shaking a bit though. But anyway, I never felt it has lack of that I hitting the target. Well, at least for me.
