I'm a LVL 90 Life Wizard and all the dungeons were really hard to get through because they take so long when you like to play solo. People today just don't have hours and hours to spend on one battle and you can't leave or you forfeit the battle!
We should be able to pause or quit and save our battle positions, not during a battle, of course, but in between floors and battles in one dungeon.
I am partially through Azteca and couldn't do it without hiring henchmen. I wanted to clear my quest log of those annoying optional quests that never go away, so I decided to tackle Waterworks, which I couldn't do at a lower level.
Well, guess what? I can't do it even at LVL 90! I spent three hours and many henchmen later to get to the end boss and die! I wasn't happy about that and I will not repeat it. It's not worth it. I won't go back and do the Helephant Tower, either.
Hard battles aren't the problem because everyone likes a challenge. It's the fact that you can't leave a dungeon and save your progress while you take care of things at home or work. You have to continue or start from the beginning. That's just not fair to everyone.
the battle I had a hard time was the water works battle my mum and I did it took for ever the last battle took 2 hours but we pushed though and won the battle and got great stuff
mine was also in sunken city with grubb and i am death do it was HARD.Then i waited until i was a master then i best them with my secondary school myth and the zeke's quest in wysteria isn't worth it.

So far I would say without a doubt Sunkin City. I tried soloing it at a level 18 and just kept dying. Finallly I asked a friend for help and he and I got through it. I HATED that place.
The trial of spheres. I absolutely hated it. I thought I was done half way through and then I have to defeat another boss.....Why is we even have to do that?
Golem Tower is hard at the lower levels. I usually wait a while before I try that tower. Build up health and mana, and get some strong spells. If you have a few crowns to spend, you could get a low level henchman to help you too.
And Prospector Zeke's quests are strange, but here is one link that gives some info on where to find his stuff:
The hardest quest for me has been The Trial of Spheres in Celestia. It has a lot of puzzles and really tough bosses.
Yeah, the Trial Of Spheres was tough... Too many puzzles. LOL. And those tons of fights you have to fight before the main boss... My brother saw that boss that said: "You have charmed your way into my heart." Then, he stuck his tongue out and said: "That's sick!" LOL
My hardest quest was Maito I always use Centaur at the wrong time and then he use a spell and I almost dead and I have no pips to heal! I took like 14 tries!
If you can guess my secondary school I will give yo a Cookie!
Well, I am not the highest-leveled wizard in history, or the best combo of schools, so Sunken City was worst for me. It just took forever, ya know? I am impatient.
Hardest quest... this might take some thought... No, it doesn't! Weird Science. Katzenstein and his helper both have storm resist, and i'm storm... But I did find out meowairty is myth, so yay!
the first dungeon in krokotopia. I was always this close to finishing it, but then I had to log out. I must have tried about 17 times before I FINALLY managed to complete it in time. Dungeons are a lot easier for me now, though!

I just found out I didn't do something right and have to redo it!!!
I'm surprised to say that Xibalba wasn't tough for me.
I actually think that the hardest dungeon is Kensington Park before it was shortened. It was a tiny bit tough for three level 80's. I think now that I have avenging fossil I can do it with my grandmaster life.
cool hope you are doing good 
I took like 14 tries!
