Yesterday I struggled in Gold I and made a video of it. Came up short of Diamond III and even lost rating. Gold I is definitely the toughest rank to get through IMO. Was last season as well. At least among the ranks I've grinded through. Never made it higher than Diamond III.
Today went quite a bit better but I forgot to record! I did remember when I opened my daily reward chests though. Not too bad really. Gold foil and a rare.
I kept playing some this time. Doing okay in Diamond III so far. Hope I don't jinx it. :D As of now I'm actually about 1/3 of the way to Diamond II. I don't have enough CP to go to that rank though so I'm not really striving for it. Would still be awesome to make it though!
Keep on grinding everyone! :)
