Might be one click to install it, but it doesn’t immediately start working after that, at least according to what I’ve seen. WINE and Proton work well in general, but I’ve seen problems when it comes to LoL specifically.

I used Windows before and was against Linux because it felt too difficult to get into. That was before I upgraded to Windows 10 and found out that something or the other broke windows every 3 or 4 days. Linux is very easy to fix and doesn’t break often in he first place, and as it turns out isn’t even very hard to get into. I have much more confidence getting into server management software now that I switched to Linux and it has been immensely helpful in other cases too, especially with eh recent developments of WINE and Proton.

Yes, there are versions of WINE and Proton that are specific to running LoL, but it’s still somewhat of a headache to get running.
