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.
Well if you think about it, since we farm the plants the plants win at the end of the day. Their offspring are more in number even safer in farms compared to wildlife.
And this is why you should install windows to a docker container on your server and not let it touch anything else. Link to GitHub repo.
