Now I've only played some low level quests since the update - namely Catacombs and Waterworks - so take this with a pinch of salt but:

1) Elite doesn't seem to have got any harder.

2) It seems like 30% of mobs have a Crown and mostly this just means they take 1 more hit to kill.

3) ANY mob can be a Champion - Oozes, Spiders, Quest NPCs {Librarian Guillaume in Catacombs - He still got one shot btw!}.

4) Zombie Champions can be a real pain to a Staff Acrobat!
Why is it that every Champion I actually noticed in End-Game Marguerite was a Zombie? {80% of that quest if not more are Skeletons!}.

5) With all those Champions {even in Friar's Niece I counted 3!} I didn't see a single chest!


Feedback

1) Reduce the numbers of Champions - 30% is way too high!

2) Buff the remaining Champions better!

3) Make only intelligent creatures able to be Champions - No Champion non-named Oozes/Spiders etc.
Preferably also keep Champion status away from unintelligent Skeletons and Zombies - Most Undead quests have a few intelligent Undead around!

4) Weapons breaking is a personal bugbear of mine - If a mob has DR already it shouldn't get more DR!
