Well the community certainly has been active since the PTR went up. Bashiok has given us some guidelines for posting as follows;
??? All post should have a subject line that clearly describes the bug or feedback being given
??? Use the search feature to ensure a thread doesn't already exist before posting
??? When reporting a bug include as much information as you can, including steps to reproduce it if possible
??? Any non-constructive posts may be deleted and the poster's privilege to post revoked
??? This is a chance for you to ensure the 1.13 patch includes changes and balance tweaks that you think would lead to a better overall experience. Getting the information to us in a clear and logical way helps us understand your view and makes it easier for us to collect feedback for any potential updates to the 1.13 patch before release.

I will summarize the most popular threads below to simply it for Bashiok and anyone else who doesn't feel like scrolling through 200 threads to review the voice of the community.
This is not my opinion although I may mention my opinion as I describe the threads. It is a list of the most popular thread issues direct from the PTR forum.

1) Runes need to be more obtainable. Although we appreciate the increased drop rate it simply is not enough. Aside from upping the drop rate gambling runes, rune shrines, hell forge quest reward upgrade are just some of the ideas that have been brought up.

2) A new way to gain experience would be nice. The most popular way seems to be to make the cow level give more experience. There have been some other suggestions , one of which that jumps out at me is an endless end game dungeon and most would support it but I doubt it is something we will see.

3) A way to stop bots spamming in games, channels and farming items. A captcha has been suggested but there seems to be a large % of the community against the captcha idea.

4) Bug fixes. While the biggest include TPPK, Aura stacking and drop barbs there are a number of minor bugs that would be nice to see fixed as well. There are a lot of details in these threads.

5) There is a concern hat with respect, the removal or Iron maiden and the nerfing of souls the game is becoming easier. I am sure this is debated although I have not actually read the thread myself.

6) I am sure everyone would like to see new items as long as they are balanced with the ones we currently have. The more choices the more unique our characters can be. New Unique and Rune words have been suggested.

7) The enigma/tele debate rages on???

8) There is a lot of discussion about skill (single or tree) balancing. Here are some of the more popular threads. There are a lot more! Some of the things that keep coming up are Assassin Martial Arts and Druid fire skills,

9) There is little debate that the community no longer supports the way the Dclone spawn and Annihilus charm is obtain. It seems to be felt that it currently promotes duping. Although most players appreciate the experience and charm itself we would like would like to see this changed.

Although there are a lot of threads that are not included here and may be some ideas that do not fall into these 9 categories, I think this covers most of it. For those of you reading this please bump this post so it can be used a resource. For those of you who have threads you feel should have been including please add your thoughts to one of the posts above. They are the most popular, which means most read and most likely for Blizzard to take suggestions from.

Lets cross our fingers that a good % of these categories get looked at.
