In brief, then:
The Living Story finally came alive, almost literally with that full-motion cut-scene with Rytlock. That was a real surprise and a very welcome one. More of those, please. Also I took to new Charr character Rox right away. Just give me those huge green cat eyes for one of my Charrs now. I'll pay you good money.
The nursery instance was exactly the right degree of hard. I completed it without dying but I was downed a few times and it looked touch and go for a while. I hate having to restart storyline missions after a death because it completely destroys any narrative involvement I may have had with the story. If my character died, the story is over. Getting up and carrying on as if nothing happened just doesn't do it for me. So, win.
WvW - The removal of culling is game-changing. The combination of that and the (really rather pointless but inevitably addictive) ranking system meant a complete change of behavior in WvW, which last night resembled nothing I have seen before. I loved it. Mrs Bhagpuss was not so keen. It will settle down over time to something more in the middle, I'm sure, but for now I'm going to enjoy it for what it is - chaotic, hysterical mayhem.
An unannounced but very welcome change was the rolling-out of the increased challenge levels tested last month to more big events. Claw of Jormag last night was vastly improved. I particularly admired the way that Ice Elementals had been persuaded to cast continual AEs on the "safe rock". So many downed players! There were a number of clever changes along these lines that I noticed and the whole thing was riotous fun again in the way it used to be back in September. Whether that will last, we will see. Players do have an almost limitless capacity to game themselves out of their own fun so I imagine new strats will soon be discovered to re-trivialize the event.
That's it. Can't stop. Got a Norn to help next.
