What are you paying a subscription for?

What maths are these?
Subscription is £7.70 or $13 a month. That's £30/$52 per patch or £92/$156 per year.

I get at least 70+ hours of content each patch, if not significantly more when I'm really into it, which is what I would get out of any single player game, which would cost around £50-60, so almost twice as cost effective.
