Balance druid, advices

Hello. After playing as resto for few years, i decided to roll a (b)oomkin, and for my surprise, i loved it!

I was asked to play as balance for my guild, and i decided to accept, eventhough i dont have much expirience. I went to the Orgrimmar training dummies, and i was able to do around 10-11k dps.
For me, it was an great success, but i got told by my guildies, that i should be able to do a little more.

I checked websites like EJ, and got many tips from it, but the dps was staying at 10k:ish.
First, heres my armory http://eu.battle.net/wow/en/character/stormreaver/or%C3%ACn/simple .
As for my rotation, i start with Starfall, followed by treants, and after that, Insect swarm and moonfire, and Starsurge. After that, i either start doing starfire until eclipse procs. When the eclipse procs, i refresh my dots, and start doing wrath, and then rinse and repeat.

I was told to gem / forge haste, well i did, but the result was still the same.
So if theres anything i need to change, switch or anything, i'd like some assist on that.

Thanks :)
