The main issue that's been brought up is that it makes pugging even more of a cluster!@#%. This is unfortunate for those without statics, as you're almost always going to full against a full party. While this is functionally not all that different from before (Loot has to drop first, so at least everyone gets their chance now), it also means those who already have their gear aren't barred, let alone discouraged, from rolling again.

For statics, loot can be funneled however. Depends on your static. Mine have decided on "if it's BIS, roll", which is pretty fair imo.
