The game feels different from a month ago

Not long ago I played regularly the game and I don't wanna tell I was good but at least consistent. Was able to carry at c3 2's without many problems. Then I stopped playing for about 2 weeks and it looks like I forgot how to play. Nothing changed about my setup, just 2 weeks off and I can't play like before anymore. Is there any updates I missed that made the game weirder? If not, any tips that can help me? Thanks in advance, I'm desperate.
