Ruin wings would still be secondary to Saint 14, there's no comparison to the safety of a bunch of enemy's holding their hands in front of their eyes. If the wings worked consistently that would be great, but clearly they don't. I am currently forced to use wings as I just had the raid gauntlets drop and of course leveling them is a chore, but once they are maxed I doubt I will use wings much. I can always buy heavy synth, but the value of the saint 14 perk - priceless.
