In a popular game i used to play, the monsters had a chance to spawn a paragon version of the mob, which was basically an elite version of those mobs with elite loot and a chance at a rare paragon thingy, it was kinda common if you were farming those mobs for a while, within an hour you would see a handful of them.

Another game i used to play they had parts of the map with what they called a "champion spawn" basically an activated pad that started a gauntlet of spawning mobs that got stronger and stronger(wasn't just mass mobs, they had stages of an elite after 5 stages etc..) to the kill a boss at the final spawn that would spawn a chest, all the mobs were lootable, it was out in the open world, some champion spawns were fixed in spots other spawned randomly around.

It would be nice if there was a group finder for each dungeon and the daily, they're handy and don't bog up the chat, i mean if this game releases and lots of people come to play it's just going to be an ugly chat mess without it, it might help people get groups to farm dungeon instead of solo, just being able to see people actively looking for group in those finders without needing to use the chat, i mean there could be a new channel added to chat after that aswell "lfg" that pops up with an automated "dirtyflamingspider has started a lfg for wolf cave <click here to join>".

Dungeon loot should be good, it's a dungeon, it should be where you see the top tier gear/mods on gear for that level, i hope the dungeons dont end up like solo loot after this patch where you see more white and green than everything else just because people were talking and making the comparison of how bad the loot is for solo play compared to a dungeon.
After looking back on forum threads i couldn't find the one asking for dungeon/group loot feedback and the info about how the loot was improved in dungeon.

Am still looking for this patch notes for what's coming up next.
