Why does playing Dota 2 feel like trying to be a glorified advanced calculator?

(Serious)

Going into Dota 2, it really felt like everything was so romantic, novel and creative, but as I gained my 4000 hours, the more it just totally started to break down into feeling like trying to play Dota 2 to win is to try and be a glorified advanced calculator. I'm not going to argue with anyone about how it can be thought of differently and that you can choose not to play to win because that's simply preposterous to me; playing it for fun has only ever removed the fun for me. I know this might be something not even unique to Dota's fault, and that it's really more of like a general psychological topic, but if I could find some kind of way to just somehow go back to feeling that same love maybe that I felt that at the beginning of going into it, or something of a better-feeling result in an alternative, then that would be nice. And don't tell me that dota isn't for me, because this entire post already makes it obvious that that is a conclusion I've already considered and came to.
