What part feels weird for you? If it’s the mouse side of it you can play other RTS or MOBA games that you don’t have the muscle memory on to start connecting things, if it’s the keyboard you can always remap them to something more comfortable. I remapped my abilities to the home row instead of 1-5 since it’s more comfortable for me and doesn’t mess with my LoL muscle memory.
