I’m just curious. I always cringe when I think about the insane amounts of money I have spend on league at this point. Don’t know the exact number but it’s probably around 300 euros. Now, I haven’t bought anything in like a year and I don’t plan on buying new skins, but I just think about how much actually useful stuff I could have gotten with that much money. It’s one thing to maybe spend 10 or 20 bucks on one or two skins for your main champion. But most champs that I have bought skins for I don’t even play anymore.
Im playing the game for 10+ years at this point and I’ve definitely spent a lot of money on it, but I like playing League therefore I don’t think its wasted money if it makes the game actively a better experience for me. So my answer would be: 0$ wasted, at least a few hundred to 1000$ spent over way more than 5000 hours of playtime.
