Why does Replica High Allagan Coat of Fending still have red?

[Bourne_Endeavor]

I'm more bothered by the fact that my ACTUAL High Allagan gear, which I got from second coil, can't be dyed. :/ I know SE has a fetish for invalidating old content and then later throwing relic/roulettes at it as a bandaid, but this feels more direct than most cases of saying "Don't even bother running those".

Actually, if I'm not mistaken, in order to get the dyeable High Allagan gear, you need mats from Coil. So the reason they did it this way is to force the crafters to run Coil and keep it alive.
