Dawntrail's mediatour dungeon was already cleared without healers.

[Absurdity]

There was a vain hope after they claimed they wanted to make the gameplay more engaging at the PAX media tour.

Though they've also had a history of not living up their promises, so...

You mean like how they told us they're gonna be increasing incoming party damage, and healers are totally gonna have to heal more, for two expansions now?
Imagine my shock.

At this point I'm getting the feeling that when they say "We're increasing the damage enemies deal." they mean "Level 100 mobs are going to deal more damage than level 90 mobs."
Yeah, I could've figured that one out on my own.

Ran holminster for giggles ya, reminded me why I dont remember it. Same crap I have seen mutilple times. 1 or 2 hard hitting mobs pulled into a large pack smaller ones....gets old fast. Only one trash has ever impressed me enough to be remembered. Final pack in Hells lid before the last boss. Watched it quite few times one shot a tank and too this day nothing has matched it. Too me every trash pack since first dungeon or last dungeon is a watered down wannabe of that trash pack.

The serpents at the end of Hell's Lid have an untelegraphed cleave buster, it's the only "recent" dungeon I can remember that actually has the enemies do more than auto attack and occasionally do a laughable AoE spell with a 10 second cast time.
