Fair enough, that point is conceded. However, that wasn't the point of my original post. The point of it was about games being balanced in a way in which progress is gated behind high walls that either takes forever to get over, or you can pay to get over it.
To the point of DLC and expansions, those are specifically to access additional content that wasnt in the game at launch, not to get to content that's already there (unless you're 2010 era Capcom with their disk-locked content), so it's a noncomparison in any case.
Subscriptions are also another point of debate, which I can admit is hit and miss. Is the sub worth the service? Am I getting enough bang for my buck? For me personally, for WoW at least, it is. I can play the entire game, all of its content, without feeling like I'm being stonewalled every two days like I do with most mobile games. The only thing stopping me from playing those higher endgame modes (mythic raiding, 20+ keys) is my own lack of skill and lack of desire. I can't pay money to improve that.
So, again, my point is how most mobile games are balanced and designed around "encouraging" you to pay to progress. It's no longer about who has the most skill, but about who has the most money.
