The first patch helped a ton, and it seems like there is still a lot of people leveling all the time. There's almost always a keep siege going on at lower levels (T2 or T3), I think the biggest thing that hurt WAR was releasing it too early. Basically the game is a lot more fun now just because a lot of the annoying bugs have been fixed, class balance has improved a lot and people aren't just scenario humping anymore. I got my friend who was playing the runes of magic beta to try and she is enjoying this a lot more, I don't think the game will ever achieve a huge playerbase like WoW but I doubt itll go under as it seems to have a smaller devoted playerbase.
This patch does sound good too, the first one improved the game a lot so I hope they can continue to make things better because at its core its a very fun game.
