Awesome... I got it soon after I got home. My strategy over the last few months was to save up for 9 exotic engrams... My reasoning being that there are 7 chest pieces, and three of them are Warlock chest pieces. If I have two extra that gives me room to afford non Praxic duplicates. And in any case, there is a max of 9 slots, and possibly rolling consecutively will improve my chances. After a grueling grind, which ultimately included creating two new characters, to get to 207 MoL exexactly, I began rolling. I don't remember the order but on about the 7th roll I got that wondrous chest piece, crafted by the Praxic Warlocks. I got two armamentariums, a voidfang vestments, Starfire Protocol, crest of alpha lupi x 2, Praxic fire, lucky raspberry x 2. I was getting nervous and I finally heaved a sigh of relief when I saw it appear on my screen. Can't wait to max it out.
