After playing around with the system on the PTR I think the system is a great improvement to the game. I play on a server where the only heroics ever run are the daily and ToC so it's rather hard to farm badges, this new system should make it much easier to get badges.
I also enjoy the new disenchant option on rolls during the dungeon. It allows for items to be disenchanted even when an enchanter is not present. Or at least it seems that way, I can't really be sure if it requires an enchanter to be in the group or not due to the fact all premade characters have enchanting. It doesn't mention the need of having an enchanter for it in the patch notes though so we can assume that it doesn't require one. This option is really useful because it uses the blizz greed roll system to hand out enchanting mats so everyone gets a shot(I have been in quite a few groups where the enchanter refuses to hand out shards at the end). Another great part of this is that it also allows you to DE greens on the spot without having to find an enchanter who will do it for you.
Overall I think this new dungeon system is a great add to the game. Anyone else have thoughts or opinions towards this new system?
