Sah-weet and thanks for all the tips!
I've been finding loot drop and xp runes are hard to come by...keep getting ones for duel-wielding and other class-specific/alignment stuff my human commando is not LOL!!!
Oh, and I was indeed very close and you were right. Got 100 leaders and 100 blueprints last night but it definitely wasn't with the one character I was using as I don't think I'd done that many with it yet. Ended up spamming about ~10 low-cost blueprints when clearing my inventory and it unlocked.
Went from 36 to 43 last night with little effort, might as well do 50 and I somehow managed Unstoppable Hellheim while doing a private co-op match which I never thought would happen due to the crazy number of enemies. The game has already been throwing level 50 enemies at me. Crazy.
