1) I don’t know what client you’re using but no matter which one it is, you need to just dig into it a little deeper. You can upload any engine you want and immediately use it to analyze your game here.
2) Most players here are of the non casual, tournament variety and use an external program such as Fritz 15 with an uploaded engine like SF Dev to analyze their games. It’s deeper than any analysis out there and if you want to go the free route you can just upload your game for analysis on Lichess.
What you’re complaining about here is a total non issue. This isn’t Chess.com. Most players here are relatively computer proficient.
