I'm still playing, but not as much as in the beginning. But that's to be expected with a fresh game.
But lately, after focussing on WvW solely and my server finally getting an alliance with TS started, I'm playing a lot more. That part of the game is really fun although it is a bit soured by the broken matchup system that sadly has been ruined by allowing free server transfers for a way too long period.
Every week some top-servers lose people due to their long queues. These people go to lower ranked servers with lower queues and make them stronger than their rating would reflect, thus dominating the lower brackets. And on the other hand these high ranked servers with lots of attrition are left bloodless and have no chance, after the major forces who brought them up there have left.
I hope they shut that vicious cycle down soon.
Other than WvW I don't find much to do anymore. The PVE was fun at first with the DEs, but got stale very quickly. My main is lvl 76 now and I haven't done PVE since lvl 40 or so. But that's not necessarily the game's fault. I've always done PVE mainly to get to the lvl where I could finally PVP. Therefore I really love the fact that I don't have to here
But as WvW is really fun I've definitely got my money's worth now and will do so in the future. And I hope after we've dodged the latest shooting star server that steamrolls the field from the lower brackets (Miller's Sound seems to be the place to be for German language WvW fans at the moment...), which should be at the end of the week, we will finally be getting more balanced WvW in the lower midfield brackets. That is, unless some top server alliance decides to move down to a server with lower population again...
