That’s fair enough, but do you not think that by adding additional perks as you have suggested with ‘dash’ could lead to even more over powered units and more saving/DDA problems with players? The current skill point system allows for small amounts of spending on our 3 key attribute bars. I perceive the levels more as milestones of training. The additional 10 sp for each mission is hugely powerful and for me means that ultimately I will have super soldiers, which in turn with make me complacent and become a weaker player despite me liking the extra points.
However, I can see that your ideas has much merit if implemented with lots of very gradual increments, e.g. dash is only 25% at first. But considering the amount of work required to develop a system like that and balance it, as well as bug testing; I would assume their is a much greater priority for other work to be completed under the current circumstances of the game development needs.
