I have problems to intercept literally anything and its pretty anoying

Since the new Patch the game feels extremly slow and defenders take an internity to turn, that you start to belive a stone has more flexibility. And on top of that i just cant get in to duells anymore and it seems like my openents have the same problem, since my games finish like 6-8/7-9 Any tips (And i dont/didnt run 91+ depth)
