From this post, are you saying that the NPC's on beta are deliberately weaker than they're intended to be so that the levelling bracket isn't punished? I always thought - and it certainly seems that way if you level through the brackets - that the NPC's have their own stats based on the bracket, not a direct scale down based on the max bracket... maybe I read the post wrong!
As I said, it's complicated, but essentially in order to make the bosses appropriate difficulty at level 90, they have to be either very strong or very weak at level 85. We went with the latter. Check them out at level 90 and see if they feel better.
Could you take a few minutes to address the concerns in the main post as well please? AV just isn't fun now and if things stay the way they are looking to stay based on the beta - won't be fun for Mists. I think a lot of players all over the world would really appreciate it.
There are two big relevant topics for Alterac Valley. One is that the BG is scary to work on. What I mean is that it was super ambitious, probably over ambitious, for when we released it. It is probably the single most complicated design in WoW in terms of how it was built. Some days I am surprised it works at all. Brave designers run in terror when they peer into the dark recesses of AV to try and figure out a bug or even dare to hope to understand how many of its complicated parts work. We've known for a long time that AV needs to be rebuilt. The good news is that we have many more powerful tools these days. While they still aren't as complex as AV, the new BGs took a fraction of the time to build. I think we could rebuild AV with less duct tape and baling wire these days, which in turn would make it a lot more reasonable for us to test out changes.
I'm sorry I can't burrow into every single suggestion, but I do like the idea of turning the (non-scaling) trinket into a tabard. We do appreciate all of the feedback. We really do pay attention to it.
