I'll agree that where as last patch with Arbor etc I definitely felt like I had to try and be more cautious until I was able to farm some new gear, this patch I came in already able to pretty much heal the whole dungeon with HoT's so long as everyone else is doing their job correctly. I think I was around item level 208 when they dropped and its only getting easier as I re-gear. I don't have a lot of issues with the bosses themselves its just nothing seems to hit hard enough to present a challenge and aside from a few rare things (stepping in the same circle as your debuff in the 2nd boss of lost city) nothing seems terribly punishing if you mess up. At best its inconvenient like when people don't face their clones at the wall and force you to dodge the cones. Even then, I got hit directly by two the other night that I couldn't get out of in time and still didn't die.
Also maybe this is just me but it officially bugs me that the areas between the 1st and 2nd boss in both dungeons are essentially the same: circular platforms with drawbridge like effects to prevent mass pulling. Its primarily just a difference of aesthetic and mobs but with a very similar layout and putting it at the same point in each dungeon only made it all the more obvious. And with Lost City it grates on me because the very next area is /also/ circular platforms. It just didn't do it for me. I did love the look of the upside down bits of Antitower but I wish they'd been, as others have said, more involved. Perhaps to get around some gates we could have used a jump pad to get onto the 'ceiling' and fight mobs there before jumping down on the other side again. Something.
