Now that RL is free, there were over 1M people playing yesterday. Normal average was 200-300K.
All progress has been reset. I was back to level one after being 300+, not that it really matters. It is just causing some really one-sided match-ups until I win enough matches to be ranked.
I already have a ridiculous number of blueprints that I will never use. You can trade them up like other items. I do not know if you can trade them to other players. I would guess so.
