They should at least remove or reduce the cool down on Blink, or allow you to use Glide while it's on cool down. Why even have it as a jump ability if you need to wait a few seconds in between uses, leaving you without any jump ability when you might need it? Why not take it out of the Movement Mode section, and put it as a third Class ability on Voidwalker, or place it in one of the 3 subclass Attunements, and let it work like Icarus Dash?
