The auction house always seems to be suffering from a drought.
Part of the reason is that the only was items make it to the auction house is if someone buys a pack (or packs) and posts items for sale.
Any players/cards that are built from MSP sets, or earned from challenges/objectives/etc are non-tradeable.
Any packs in the store that guarantee a player/card from a specific program is non-tradeable.
Until this model changes the auction house will remain slim pickings.
I know the NHL market is not nearly the size of Madden but at least there are multiple ways to get players/cards in MUT and the vast majority are tradeable. Other than limited edition cards they are often reasonably priced and always available.
Would be nice if:
Every program had dedicated packs that contained cards/players from that program and they are tradeable.
Every program had sets that allowed you to build any card released in a program, not just MSPs
Every program had a way to earn specific cards through challenges rather than build them - these rewards could be non-tradeable
Coin rewards were such that you can reasonably grind things out and earn enough coins to buy the cards/players that you want
Just one man's opinion.
