They've said before that the reuseables are not a mechanic they intend to repeat, so it seems unlikely there will be a lot of BoP purple consumeables at the new tiers. You may want to pick up a biochem alt to make stuff for yourself, but it doesn't seem like there will be any skill you need to have just to be able to use particular must-have kit at the endgame anymore.
Thanks for the quick reply. Regarding reusables, even if I did have an alt that can make them, my main would need Biochem at 400 to use those items, correct?
What about Exotech stims etc.? Don't they also require Biochem to use?
