It's a terrible return on your investment of time. You can walk over to the cat claw and get 50 MGP for less work than trading the echidna card.
50 is 50 and adds up to a lot of people losing rolls on a card they don't have. It's like rolling on gear just to vendor it for gil. Now, if they were to do like in FF8 and allow you to convert a stack of one type of card into a rare item, it would be worth it. but not for 50 mgp.
If a player already has the card, allow only greed roll. If you they don't, allow Need. Not sure why they changed it in the first place. This just turns the cards into 24man minion rng. I guess to make people do it more but how about buffing the actual minion drop rate instead. It doesn't drop.
Like I said previously...thanks to the damn card, the minion hardly drops at all now..it's always the card. As for the person above me..yeah that one.
For that reason along I wish I could force myself to roll a Greed 1. Even if I could Need, I used to always Greed, so I can sell, GC turn-in, make material, whatever. But recently I would only want to "pick up" the item if it is dropped on the floor, but I don't necessarily want to Greed above someone else that may actually use it.
but it's my only source of gold saucer points since I always lose them in mini pot.
