Having a tiny amount of slots only means you focus on the highest value ones. It is antithetical design to have a bunch of weeny perks with low cost but very limited slots - you’re incentivized to just run the highest power and impact possible.
If I want to run a bunch of cheap perks to fill up my capacity, then I should be able to - why have a lot of cheap options available otherwise?
People should be allowed to have options and choices - either take high power perks and don’t use up all my slots, or use up all my slots efficiently with a wide variety of perks of varying costs.
Oh, and please increase the distance and speed of slide for both sides.
