The exchange doesn't magically fill with DOFFs for purchasing. They have to come from somewhere.

No, the exchange will be filled by people turning their brains on and using doffjobs while using the doff system. Seriously, I never had any trouble making purples, season 7 didn't remove any free way to get it (it wasn't free) but it removed the easy, already overpriced (500 dil for a random geologist or warp theorist, seriously?), and inefficient system. They just made it even less efficient.

It won't change the game, except for people not willing to learn the doff mechanics.

Anyway the markets already gave their verdict: purple, blue and green doffs are worth nothing on the exchange. It means they have very little value for people, and indeed, I don't see the necessity of having purples, except for your active roster, since you don't need them as consumables anywhere. Tactical and security whites will still have some value but the rest will be completely ignored since purples get in everyday without any sink to balance that. More purples every day and no sink can't make them cost more.

This was a really dumb change. It was already expensive to grind up to a purple DOFF, and the price to do so now is utterly ridiculous compared to what the DOFF tier rewards cost for buying them with dilithium.

The grinder is RANDOM. I didn't like getting purple chefs from it before S7, and I'm not even going to risk it now, because the cost is stupidly high for something I have no choice of what I get.

Converting that dilithium to zen and buying a pack is easily a far better option right now. So why grind out a potentially useless purple instead of buying an entire DOFF pack with the same amount of dilithium?

Resorting to calling people who don't agree with you stupid, lazy or bad discredits your argument. You did this same thing in another thread, for the same reason. PWE made a change to the game, reducing Dil supply, to squeeze the playerbase for cash, and you were and are trying to defend them doing so.

It's a silly position to take, and resorting to insults to do so demonstrates just how little else there is for PWE reps to stand on.

And Cardassian, but Bajorans can get the highly coveted efficient/resolve combo.

Because he is right. They didn't take everything away. Cryptic just adjustet the costs of a small portion of the doff system.

If you are not clever enough to this... well, your problem xD

Calling anyone who doesn't share your opinion stupid invalidates your argument.
The fact you haven't been actioned for insulting other posters speaks for itself.

PWE did this to drain Dil to sell more Zen. Watching Zen tumble on the Dil XC proves as much.
