Sorry if this is a dumb question, but can anyone advise on exactly what is needed to rank up from 1 to 0. I've been stuck here for about three weeks. I've been on the first page of ranked ladder throughout that time (currently 3rd with the highest MMR on ranked). I have completed the jigsaw and then had winning streaks of 1-3 games, but the 'magic' never happens! Do you need to win more games with a completed jigsaw to make the big leap to rank zero?
