Dungeon improvements & suggestions

The annoying thing is that they have done interesting things with trash mobs in the past and just decided in Ew that they weren't going to do that any more for some reason.

I can't remember all encounters, but one I do remember one specific that I liked.
Was it The Sunken Temple of Qarn? Where there was Wasp trash mobs that could 1-shot people if not deal with quickly?

I enjoyed it simply because it added a priority list of targets making those engagements "feel" different than others.
It was a pretty simple yet effective way to add a new way to tackle a trash encounter.

The wasps were in more than just Qarn, but I think Qarn was the first one to introduce them. Qarn also introduced the "kill mobs on specific locations" thing which never got done again.
The level 40 guildhest "ward up" introduced enemies that had to die at roughly the same time (a mechanic that was, iirc, also never revisited)
And the Sil’dihn Subterrane had a puzzle where, when you killed a group of enemies in specific order, a special path was revealed.

Trash mobs can be more than just hp sponge obstacles, and CS3 has proven that they know how, too. They just need to be a bit more confident and don't let naysayers shun them away from doing new things occasionally.
