That’s a cool mischaracterization of the argument.
Big powerful racial movement abilities have cooldowns, they’re but a shadow of their parallel abilities. Warrior leap, have no fear goblins can do it occasionally. Rogue vanish? Cool, very powerful ability on a cool down for Night Elf, we see it abused plenty in high level play.
Passive movement effects for races have a clear precedent, hint - I already told you it was 2%, not over 15x that with additional benefits. Put it in non-instanced content, no big deal. Run around gold shire flapping at 40% increased movement speed with your 1.5 minute knock up or knock back. We don’t need additional power creep from races being introduced.
And again, I can care less if all racial abilities get buffed or gutted, but it should be one or the other if glide goes live. Look how straight trash Earthen racial abilities are. It’s like there’s a whole other design philosophy applied to them compared to Dracthyr.
