I don't get why people would be mad about this? Regardless of the health of the meta which from my understanding is a problem, let's not dismiss that, there's clearly a demand for ADP, and, not to mention, Cosmic Eclipse as a whole. A set being reprinted doesn't mean the card's going anywhere until it rotates. Pokemon's usually going to want to supply something that's in demand, it's basic economics.
Besides, and to be positive about it, this is good for collectors too! There's a lot of cards I'm after in the set that I'm hoping this print run either lowers the prices for or I'm able to get lucky enough to pull, since this set has a lot of really nice cards. Especially the unlikely off-chance the stars align and I somehow find Full Art Rosa. That'd be nice.
