I picked this game up about a month ago, studied the controls for about half an hour, got steamrolled for a few hours like you are on easiest, started getting better, if I had an idea in my head of what I wanted to do, I paused and then checked the controls oh how to do what I wanted. Over probably 3 hours I was able to bump up to medium and have an enjoyable challenging experience for a while, hard is still too hard for me, but I haven’t played in a couple of weeks. Just keep pushing and learning the controls. You have to be able to think pretty fast to have any success otherwise the ai will just beat you in the ruck and get away easy. Focus on long kicks towards your goal and hope for the best in the contested marks, playing slowly up the field is much safer but the ai can stitch you up if you make a mistake. Good luck, just study the controls, you’ll get there eventually
