If you do replay, I'd suggest playing Arena to get used to the various gods and items since it's just basically an open area with nothing but team fighting (that few take seriously). Also look up a few builds so you can get the hang of what the popular items are. The mode is my go to usually if I want casual matches that last 20 minutes at the longest and 10 minutes at the shortest due to surrenders. It helps with learning new gods too (outside of lanes). Some gods just do better in laned combat, like Anhur.
