I want to reach plat in season 9, and then maybe touch diamond, even if I'm just in promos

Player since season 3, I started playing "seriously" in season 6, when i first played in a team for 2 years, which ended during the preseason 8. Then, I learned with some good players the art of coaching and after this i started coaching team, starting with golds and finnaly with diamonds. I stopped playing to concentrate myself in coaching, so my game level dropped a bit, but I try actually to join another team, gold level, to start playing again like during the good old time
