I don't need the top tier of loot, and I don't like to raid.

What I do need is progression, which is what I'm paying Blizzard for.

As of this moment, I have pretty much the best gear I can get out of doing heroics, and by the looks of 3.1 PTR, Blizzard won't be adding any more 5-man content until at least 3.2.
(last time they didn't add any until 2.4)

And I'm just not willing to wait that long.
