Consider adding a server setting to make Blueprints not be consumed after one use. In YO, guilds are not nearly as large as they will be in the MMO, so I feel the resources just aren't there to produce multiple sets of tier3 armor, since the armor update, I have seen maybe 2 full sets of t3 (I suspect admin shenanigans too).
An option to have consistent BPs (Even if it only stayed with the character until death) would bring back (potentially) 50% of the armor in the game, which has been unused as of late.
