The card is simply poor game design. Its fine early on but quickly become irrelevant, which is fine but not the way the new zone/dungeon is designed.
The zone and dungeon drop lots of cards but with the trinket being terrible after raid ones it completely negates the drops form being useful.
The trinket suffers the same fate as rings as well which means ilevel doesn’t make it automatically better (which blizzard said they were trying to fix).
I have a crit haste ring with a socket for example at 385 and i looted a warforged 435 ring with master haste and it was still worse then my 385 ring. At a loss of 500 dps. Blizzard seriously need to add main stat to trinkets and rings.
