So I finished my second shroud run the night before last, and now feel I am officially an expert(kidding, obviously).
Anyway, through a comprehensive process of mostly just buying stuff on the AH, I've obtained all the ingredients required to complete my tier 1 and tier 2. I could have made the tier 1 on my first shroud run, I had the stuff then.
But after the second run I STILL do not have a Shard of Power. 3 of the darn things dropped on the first run, probably 5 on the second, but none for me I know I really just have to be patient but its so hard looking at this beautiful green-steel repeater and not being able to do anything with it!
