I did my placement games and placed in gold. Since then I'm now currently in gold 2 for competitive. I have neither received the garunteed artifice armour drop from the weekly challenge mot the have I got any from several wins after being placed. I can understand that RNG might be letting me down but not getting the garunteed weekly drop is what I believe to be a bug. Note: I'm a console player and do not own any dungeon keys for any of the expansions. I do not know if this affects the weekly comp artifice drop.
