Since this is a forum and attracts a higher percent of non-casual gamers, the most common discussion is how to max gear and builds for the highest GRift. An end game maximization strategy and very relevant with PTR and an "opportunity" to have the Monks Uber-end game builds reviewed for modification (hopefully) before patch goes live.
A lesser percentage of higher T level build diversification builds/questions. These seem to be consistently met with "T6 is not end game", "Anyone can clear T6". Build diversification is an interesting part of the game and the class. As any post, useful information is good, useless comments are just a waste of everyone's time. T5 and T6 will continue to be a big percentage of play time for most players, to level, farm, and try new builds. They are not irrelevant.
Newer players trying Monk and posting builds and asking advice. We were all there at one time, probably came on the forums, if you are reading this you are on the forum so a pretty good chance, and looked at builds, posts, vids, and asked questions. Helpful answers were appreciated, useless comments again are a waste of everyone's time.
The Monk forum was a good place to actually discuss things at a higher cerebral level than General Discussion. It was relatively free of the epeen I rock and you are a noob posts. It was a good place to go for information on the Monk class.
With the patch looming and soon to go live, there likely will be more interest in playing a Monk. Which means more interest in the class forum. Hopefully it will be a good place for Monks to go to get information and ask questions to increase their enjoyment of playing a Monk.
