I played until I had a 200+ win streak and a little over 5000 AP. I ended up around 150 and got 20 parts. Now I've gotta try and get the rest. I'm in iOS league too.
I'm up to 150 and 209 win streak. I do have one full charge and 3 singles I'll use if it looks getting top 90 is doable. Just be a lot easier to craft the weapon at that point and I really need a new heavy. That's my weak point. Im still stuck with a Pale Horse 6.5.
