On one hand the 2 oldschool leaning keys is very comfortable to perform just a lean. On the other hand the fluid lean/duck key is very useful, but I think the problem that leaning that way, the mouse can't be used to aim the weapon.
In RvS you needed to release the fluid lean key to keep your 'adjusted' felxible stance and be able to aim the weapon.
How you think to solve thet problem?
Generally I love the idea of one lean key, that operates the fluid lean+duck, awesome, but how to keep the aim available? Maybe by releasing the lean key you stay leaned (as explained with the RvS system), but the problem is, that in comparison to this fluid lean the normal lean in RvS is still much better.
I always thought about the mousewheel as a fluid lean key, wheel back makes you leaning right, wheel up is a left lean.
Pro is:
- that you can lean fluidly and lean back as fast as you want (defining your exact position).
- can move yourself as usual (cuz no key on keyboard needs to be held).
- can duck at the time and can use/aim the weapon.
- mouse wheel can be reused for other operations when for example aiming a scope, or others.
Con is:
- no fluid duck/raise.
- the mouse wheel has small stages (no 100% fluidity), which is not that much a problem.
An idea is, that the fluid lean is operated via the mouse wheel as explained above, but holding a special key makes your wheel be a lower/raise stance, while the adjusted lean keeps, that way you could just correct your height by holding this key and go on leaning fluidly when the height is adjusted (all with the mouse wheel). Pushing this special key will give you your standart stance (or pushing duck key will let you duck).
The cool thing is, that holding this key and changing the stance via the mouse wheel, can let you also raise your stance over your standart standing position (stretching).
