As many of you know, or have experienced - You’ve finally unlocked that really cool skill in your tree, only to realize you can’t use it, probably not for another one or two tiers.
I believe the skill trees should be redone and scaled, because many of the things we put points into are equipment (Carnation system, Falcon system, stasis, etc). However, are unusable, and can be considered a complete waste of research points.
Or just allow such things to be used earlier in game.
