What’s the hardest rank to climb through

I know this topic has been talked about in the past, but I’ve been wondering since the start of the new season what has been the hardest rank to climb. I’m currently an emerald player and I have found it quite challenging to climb through this rank. Recently I’ve done this strategy where I muted all and have no chat so I am forced to not talk to my teammates. And take every bad play or loss as my responsibility but I am the only one in the game full of “npcs”. What strategies do you recommend to get trough turf ranks?
