Resources being expensive for real cash is not an accident. It is a necessary balance to make them attractive enough as a one or once in a great while buy for someone with a fairly low income, but not so attractive that somebody with a relatively modest amount of discretionary income can “buy the game”. If people were able to do that more easily, the f2p (or next thing to) player will be boxed out of the game and unable to remotely compete for anything without a longterm determination that does not exist in today’s world of “There’s another game over there”.
Those f2p players are what allow freemium games to gather a larger community and userbase, so they benefit the game as a whole - in narrowing choices for the devs so that everybody benefits from a readier supply of things like ISO and HP and everything over that is gravy. It takes work to keep that balance so that the resource is tight enough to keep people chasing it, and to keep the average user from spending a modest amount of money on the game and running away with it, AND to keep the game profitable.
A choice to make ISO and HP easier to buy could easily upset that applecart by making the game LESS popular, people getting bored with it more quickly as their roster development drastically outpaces any new game development and those who can’t pay for it putting it down almost as soon as they pick it up.
Do they have the balance perfect? Almost certainly not. But they for sure don’t have it off as far as many people seem to think who aren’t incorporating these other factors in their evaluations.
It seems that you’ve been very unhappy playing MPQ for the three months or so. I may be wrong, but I think you’ve made a few posts of how bad this game is. The game is built for grinding. The game has flaws. The forums are filled with ways to maximize your roster or game play from 1* and up. If you’re not willing to spend money (you’ve always easy posted that you won’t) or patiently build a roster, then play casually.
Btw, I’m sure you can hit 10th prestige in Call of Duty in 3 months.
I’ve messed around with a couple dozen other F2P mobile games. Demiurge and D3 do a far better job of making MPQ accessible without whaling, than just about every other mobile game developer out there.
