I’ve voice most of my concerns along with a lot of other people here:
https://forum-en.gw2archive.eu/forum/livingworld/sab-bts/Should-the-original-SAB-skins-be-rereleased/
There’s one main reason though — the minis glow blue.
I myself and a few people I know have no reason at all to buy the minis when they glow blue and I can’t even complete a matching set for them, they just look out of place wearing the yellow/green/red/purple set with a blue glowing mini.
Either let us just have the rest of the blue skins, or add an option to change the color of the glow for the SAB minis, there’s no reason to isolate your players just because they’ve done the content at a later date.
