Series are here just to keep us grinding and grinding the game.
I lost 4 series in a row, where then I win 3 games in a row then lose 2. That means I've won 12 games and lost 8 games and I can't advance... ??? 67% win rate in 20 games and I can't advance ? Alright. Just because I didn't win those exact 2 games, I can't advance. And your LP gain is going down so you keep grinding even more. Promos I get, you advance through a whole division and you gotta prove yourself there I guess. But series are blatantly here to fuck us up. I don't know how else can you justify a 67% win rate not good enough to climb. This shit is so frustrating.
