I heavily disagree that these coins or the mogstation optional items are anywhere near EA cashgrab practices.
I HEAVILY disagree. And if you do, you should really look into the issues EA is causing, and what they are doing.

Do I prefer buying items with $ over getting them in games? Hell no.
Do I have the money to just purchase items from the optional items page? Hell no.
But I do find it no problem for them to set up optional items, though the prices are quite steep.
