I get what you're saying, it just doesn't make sense to assume what another man should do or not do with his time and money. He's got a complaint about a game that he might otherwise enjoy. If he's exactly as you might think, forcing himself to play a game he dislikes, I agree it's dumb. Not necessary and you should probably hop off. But if he's continued to play he may just hate that part of the game but pushes through it.
Hell, his complaint could be off the basis he has shit luck with RNG and needs to git gud. Either way, a thought out complaint from experience isn't something to neglect. It's the ones that haven't been to McDonald's that critique the burger that you don't worry about.
