I enjoyed this event and I'd call it 'good' for me.
I was fortunate enough not to have to deal with the endless queue bugs, however; that would have definitely changed my opinion. I also didn't worry about or bother with running dungeons on as many alts as possible. I only have my sorc, warden, and a lowbie NB who was my first character. I ran them all through dungeons every day. Sorc I would usually just queue solo, because heals is almost instant. The other two I usually poked my guild chats to see if people wanted to go and got a group together in no time. No issues queueing solo or in a group of four.
I never really log onto my alts (even though I should, for writs and mount training) so it was kind of nice to have a reason to log on them and play different playstyles.

Not bad as long as I had a buddy with me, we got a lot of low cp guys but it wasnt too bad since its on normal anyway.

Meh.

The rewards were decent (for other people at least...), though the “costumes” mention seemed like a lie. I was glad to get DLC motifs instead of trash like Mercenary or Assassins League, but other than those motifs I mostly got stuff that didn’t feel very exciting (very few Undaunted Keys, a few Treasure Maps and Surveys, and mainly Undaunted Plunder). In the end I did end up receiving 2 pets, but both were pets that I had actively chosen not to purchase previously; however, I was absolutely excited to get something better than Plunder even if I probably won’t ever actually use the pets. I wished the Chef and Blacksmith costume (and some new unique ones) showed up, but c’est la vie. My biggest issue was the Dungeon Finder itself. When I was able to get a group of 4 competent guild mates together, we blazed through dungeons. However, when I wasn’t, it seemed like 70% of the time I got DLC dungeons, often with people who had zero clue what they were doing, too little skill to ignore mechanics, and who were unwilling to pay attention when you tried to explain things to them. After the mid-event maintenance, we also had the issue of the Dungeon Finder effectively dying every night at around 9p EST. Having 11 toons and wanting to get the most out of this event was exhausting and generally not fun. It felt like a chore, between the nightly broken Dungeon Finder, constant DLC dungeons, incompetent players (who I’m assuming don’t usually run dungeons, but this event required it), and other plethora of issues (e.g. chat dying half the time you try to switch to Guild Chat from Group Chat). Add onto that having to track 20 hour timers for 11 characters, rather than being able to simply rely on the daily reset, and I was very, very glad to see this event come to an end. Considering how much I love dungeons, how frequently I do them, and how often I chose to PUG all three pledges (rather than waiting for guild groups), I was really negatively surprised with and disappointed by this event.

*Other*

I'm really tempted to say "Good," but that might sound a little snarky It was just nice to have some reasonable space for questing without having to dodge the AD undead-farming hordes.

I'm pleased that I got a few motif pages I didn't have. But getting them was stressful. I had one or two good relaxed dungeon runs with guildies, but due to the Steam outage and various other issues, timing did not allow for me to do that every day and because of missing ticket opportunities I *had* to do randoms when I could, which meant pugs, which were uniformly awful. My hands and wrists are in so much pain after this event due to aggravated carpal tunnel. When I can take things at a relaxed pace, it doesn't wreck them like this. When I have to zerg through a dungeon to keep up with people who are sprinting all the way, it does. So that was not only physically stressful but mentally as well, what with fake tanks getting me killed and all the rushing and nobody bothering to stop for chests and people just rush rush rushing. That's what this event created, rushing. There was absolutely no incentive for people not to.

I like random dungeons with PuGs: good or bad ones, low level or high.
I don't like waiting in queue normally; I hate the queue not working full stop.
Haven't even opened all my boxes yet (not hopeful for anything good), but my expectations are so low that it wouldn't make the event "bad"
