No one is saying oh my god ignore haste or mastery in favor of the other. You haven't touched heroics yet, and you've logged out in balance gear so I can't really look at your stats, but I'm 10/14 heroic and I run with only 13k spirit, I have 13163 haste, and 34.81% unbuffed mastery. the point of saying you should get a certain break point is because at that break point, haste is better than mastery. As soon as you get the break point, you put everything you can into mastery. That's what's said in this guide, as well as almost every other discussion about it. If it's not blatantly said, it's implied. Spirit to comfortable level > 3043 or 13163 haste with nothing in between, higher, or lower > mastery > blah blah blah. You're supposed to "be op" and have high amounts of both, especially in this final tier. In ToT, it wasn't possible to have 10k mastery, 13k spirit, and 13k haste simply because the stat budget wouldn't allow it outside of full heroic TF.
TL;DR you're doing what all the other druids are doing.
