Q: If there's no grind in ED/EDO, why don't players have the option to just buy what they require in materials and other resources?
If you don't want to do that, but gri...er, play game loops to gather them, good for you, but it's no skin off your nose if somebody else just wants to go to a broker and buy what they need? But we can't. Why not?
You still need to acquire credits by gr...er, playing game loops anyway in order to buy things, so please don't say being able to outright buy things would break the gr...er,game loops!
