Is that not because the majority of post from some reasons are just all the positives and seemingly ignore all the flaws and issues within the game too? I have nothing against people enjoying the game (but there are posters - and Retro is one - where I take what they say with a pinch of salt), I'm enjoying, but at the same time I'm aware there are things I do not like (and believe could be improved).
The 1 time event was good (when it worked), but I don't believe it was PRACTICALLY considered or well prepared for. GW2's own shard system made it a little awkward to flow and enjoy the events, as sometimes you'd get stuck in a shard where nothing had triggered, and wouldn't trigger. This would leave you wondering if you should jump out and see if you could luck into a shard where something had triggered (and hopefully hadn't missed too much of the story).
The loot issues doesn't bother me too much (perhaps because I got some), but I can see why it might bother others. For whatever reason circumstances might have meant they couldn't log in at specific times this weekend, and because of that missed out on loot (that they probably didn't realise was available). It was also clear that you didn't have to bother with the Friday Night and the Saturday Night event and could have just jumped into the Sunday night one to get exactly the same loot as someone who trawled through the lag of Friday, sat through the none eventual Saturday night. Sure this was all highlighted in the pre-build up blog posts, and is great for casually accessibility, but it doesn't really 'reward' those who spent the time following it from zero hour any more than those who just sat back and jumped in 11th hour with all their alts to grab as much loot as possible. Perhaps.
I hope there are more 1 time events. I hope Anet have gained enough network data to ensure lag isn't an issue, and that shard management is better (perhaps 'tags' could be placed on players to datamark them to certain points within the event chains so they don't get stuck in a shard hours a head or behind where they last were?).
The only real gripe I have is... DAMN YOU THIEFS!
