Length is absolutely involved in pp values of a map, just not as much as you seem to want it.
Sliders are existent in pp formula. It looks at the shortest possible path you can take. The problem is that 1: it doesnt take into account that you have to follow the sliderball and 2: a jump will always be faster than a slider.
Map length is a difficult subject because how are you going to accurately use it in pp calculation? Should a map that's twice as long give twice as much pp? Then you will soon end up with superinflated pp ratings just because that 4* map is 20 minutes. Should a map that's similar star rating but longer always be worth more pp, even if the od is lower? When length weighting was first added people complained that it was too strong so it got nerfed, now you think it's not strong enough. It's not just something where you change 1 number and be done with it.
Also you could work on your attitude.
