I've got a dalarian pattern for IA, that appears as BOE so I consider just craft it for early 50's of my guild. But I also have got 3 energized patterns for BH and they seems to be BOP.
I can't undenstand it. They're almost useless for me. By now I don´t have the matts for making them, and while running ops to get them i've got that parts from drops. (And most of them Columi). Since I can´t sell them or give them to a guildmate, I think that as soon as I get my rakata belt with augment (already got the wrist) i'll have to drop armormech for Biochem, just because Armomech will be useless for my character.
My point is: Crafting Energized items is harder that finding Columi. (First you need the pattern , then it needs to be for your class and role, and then you need the matts, that are almost as hard to get as the columi itself). So it should be BOE just for be useful (not only the patterns, but armormech itself once you've got your rakatas).
