Gaming for me isn't about HAVETOBEMAXLEVELGREAT, it's about having fun.
That's what the cake comment meant, that user thought that people arguing wanted MAX level in everything and that's why advocated for its on way to level it so you could spend point in other things and have high everything, you are keeping the cake (points on crafting) and eating it to (points on whatever else).
By constantly writing that you want the cake and eat it too you are saying that you don't appreciate crafting for its utility or the fun you have with it and is about min-maxing. Did you genuinely didn't knew what the metaphor meant?
You know, kinda like in real life.
You know what else is like real life? No magic, Larian please delete magic
