Nerfing the Itzal is a crass overreaction when there's virtually no use for Archwing in the open worlds besides moving from point A to point B. During combat encounters enemies will nearly immediately fire that missile that removes the Archwing making them useless overall. So most players would more than likely consider the use of the Archwing - Speed.
I posit that players had no choice in the matter from the very beginning because of the Archwing removal missile. It will always be better to use a fast Archwing in the open worlds until we are given the freedom of using them for combat situations.
