The Path to a Legendary
Anet has not said anything about legendary recipes changing. I don’t think they will as they will mess up a lot of people’s plans (like your own). I’d be shocked if you continued on your path and were unable to craft it due to a recipe change.
Found my own answer watching todays video. Legendary is still the way to go for those who are close. Ascended will take a long time and will have ONE stat set. Legendary weapon stats will be hot swappable to any combo outside of combat. Thank you dev’s for answering that in a very round about way.
