I think you are fairly subjective on the matter. I think everything written here, and in your previous posts, you base on your performance in your own guild. I've looked at the logs and your are middish mostly, sometimes bit higher, sometimes lower, but all in all, you are doing fine. In your own guild, mind you. I mean, i could be wrong in my assumption but you have provided no evidence for your claims so i'm inclined to think that you are basing most of it on your own performance.
Now, let's examine your posts a bit. When someone mentioned the number of monks in top300 25hc you said that his method of looking at the representation of WW in it is flawed. And you would be completely correct if we were 3months down the line with thousands upon thousands of logs where top300 means nothing. But at the current state of the game, where only a handful of guilds have killed those bosses, 300 is a lot. Especially considering how wide a dps margin is between #1 and #300.
And the fact that WW is an underplayed spec should also tell you a lot by itself. People tend to flock to a FOTM class or spec but will stick to their preferred character if it's worth sticking to. There is a reason people are shifting from WW to other specs when they want to do competitive dps. If you switch from WW to something else and end up doing similar dps with less gear, practice and effort, that should tell you something. Either WW is underpowered or it's simply too hard to play. Don't forget, you said it yourself, we are talking about top of the line players here, not your average wow joe. And if they can't master a spec, who can? Is it even possible to master? If so, is it worth mastering? As a WW you, more or less, bring nothing to the raid so you need to try much more to reach competitive dps compared to other specs who accomplish the same with far less effort and on top of it bring additional raid utility. If you can't see something wrong with that picture, i have nothing further to say.
The other thing you were talking about is itemization and how it's every WW's responsibility to do their best to itemize properly. That goes without saying, and it's a general rule applied to every class. But when your entire spec, it's gameplay, itemization and viability is based on one item, wouldn't you consider that a bit silly. The normal way would be the way of the other classes. Most of them scale linearly with gear, progressing at a steady rate as they gain more gear. But when WW is concerned, we spike insanely with weapon dmg and the culprit of all the issues, RoR. Extremely bad balancing, nothing more and nothing less. The issue is furthered by the fact that RoR also neutralizes some of the rng inherent to the viability of WW. Consider how our usage of TeB depends exclusively upon lining up as much procs as possible.. With RoR we know that we will use TeB at the end of the buff, no thinking or waiting involved. And we are certain TeB won't be wasted that way, even without other trinket proc, or dancing steel or whatever else you might have. And that makes RoR even more mandatory. It's just an insane item for WW monk, far above anything you might get in the next tiers as well.
And that leads us to the last point which is a paradox in itself. Considering how steep dps curve is between a monk with a great weapon and RoR and the one without both of those, we will soon get nerfed. Mind my words
