I don't play League of Legends, but I loved Moonlighter (from the same devs) and the game seemed interesting enough for me to check it out, but it really isn't grabbing me.

Nothing seems especially wrong about it, but if I had to say what exactly made me give up, it was an encounter with multiple creatures were there wasn't any opposite elements for me to engage with the main mechanic favorably for me. At that point I felt like the game wasn't trying to make it interesting for me and just putting barriers, it didn't feel fun.
