Both [Glyph of Momentum] and [Glyph of Counterspell] should have been integrated into their respective spells by default, because, far from restricting, they added more possibilities...
Regarding [Glyph of Momentum], that could be fixed easily by saying:
[Blink]: "Teleports you 20 yds in the direction you are moving/trying to move or facing, unless something is in the way. Also frees you from all stuns and bonds"
This way, if for example you are being knocked back and you want to [Blink] forward, you only have to push the "W" key of your keyboard at the same time you cast [Blink], et voilà, you are teleported 20 yds forward even before you fall to the floor due to the knockback...
