It only took 4 patches, but finally, it's starting to feel like we've gotten actual expert dungeons. I don't remember a single level 70 dungeon whose final boss wiped my party in the first week, until now. The Burn's second boss almost did my group in, and the final boss took us out three times before we all got on the same page. Same with the optional dungeon - the final boss was interesting enough that we wiped once before figuring it out.

I like that. Finally, some dungeons that actually have earned their title of lvl 70 expert. Or at least, that's the right direction to be going in. I do hope that future dungeons that end up in the expert roulette continue this trend. This is what I had hoped for when asking for a gradual step-up in difficulty.
