There the real grind begun and I had to try like 6 times at rank up game and falling back to mid Diamond twice. It took about 70-something wins in total to get to Crystal.
Few other friends finished their grind and also agreed that Diamond too longest (mostly over 100 wins total), before that you have more carry potential but it will weaken the higher you get. There will still be unwinnable games and the game does try its hardest to cut your win streak down (my first Silver to Gold rank up attempt was in full high Plat game).
