Considering the large number of people, I thought there were very few disgruntled voices.
It got off to a bad worrying start for me - my client crashed the first time everyone rushed out of the hall. I restarted a few times during the event whenever I was in a quiet place and that seemed to prevent any mid-battle crashes. I'm planning to play these events as "single life" (if I die, I quit the event). We'll see if I actually stick to that policy when the time comes
I almost missed out on the first task - I went to Mistas first (got thrown for a loop by the "central" clue), but had been to the chaos moongate earlier in the day and noticed an NPC hanging out there so tried it next on a whim.
The sheer mass of balrons was stunning - as well as how fast a few score heavily armed heroes could plough through them. Because I was hanging back a little doing resing and healing and throwing EVs to clear the path of regular spawn, I almost ended up with one of the books - I was actually staring at one in the corpses (looking to see if they had chests or T-maps) wondering if it was normal for Balrons to have books when someone else snapped it up. I'm sort of glad though - I would have had trouble accepting a half-corrupted lantern
I didn't encounter lag very often all things considered, but when it happened it seemed to always be trying to res someone. Twice I missed the res icon and clicked invisibility instead (which must have looked very anti-social).
I couldn't find my stockpile of cards from past years and "to my one true love" from this year seemed a little too forward to be passing out, else I would have randomly given out V-day cards to more glorious ladies in attendence.
I was pretty skeptical going in, but was impressed with the numbers of people, the playability (it was fun to get swept up in the tidal wave of heroes swarming down the halls) and the general nice spirit of it all. Thank you for an evening's light entertainment.
