You my friend are a complete nubcake. I've been playing Balance Druids for 3 and a half years now and i can tell you, Balance Druids are at it's best right now ( except few nerfs like the impending Celestial Focus )
Indeed, at times FEAR STUN and especialy SILENCE can be very annoying at times, but besides SILENCE, FEAR and STUN can be dispelled every 2 minutes ( If you have Medallion of Alliance as i do )
Did you read the news where Blizzard totaly mentioned that 1v1 PvP is unbalanced but 2v2 or more is!? Get a pal in BGs ( I suggest a Resto Druid ) and u will rock their world. Also, add Glyph of Insect Swarm and Glyph of Moonfire in your Spellbook. I deal like 1.2k damage every 2-3 seconds while casting something else! Also, make sure that before you go in battle ahead, add some hots on yourself ( if playing alone that is.. ), also, u don't have to use Starfall and Tree Ents at the same time... That's why it has a cooldown. You'd think Blizzard adds cooldowns for fun mate.
I also checked ur talent tree, and OMG WTF!? First of all, you have Nature's Reach! I was like WTF MAN ARE U EVEN PVPING!?!? Second of all, you DONT have Brambles! I was like WTF MAN ARE U EVEN PVPING?!? Third of all, you have Improved Fairie Fire! I was like WTF MAN ... u get the point. U have 1/3 Dreamstate also a mistake, i mean comeon Dreamstate is like the main talent behind the Balance Tree, and since u barely have 450 Spirit i suggest u respecc 3/3 Dreamstate. WAIT I AM NOT DONE! You have big problems in PvP and I KNOW FOR A FACT THAT DRUIDS ARE BEST CLASS IN THE GAME and i cannot belive that ur QQing. But on the other hand man u have IMBA Talents. You have ECPLISE, another PvP Mistake ( especialy if u are playing in an Arena Team ). And you have Gale Winds which is like basicly usesless without Typhoon and well you dont have typhoon to pushback enemies so that they stop casting something or simply run away from melee DPS.
WAIT I AM STILL NOT DONE! You have IMPROVED MARK OF THE WILD. Dude thats like the worst talent ever if you are not RESTO DRUID. And you dont have Nature's Focus so that enemies dont pushback ur spellcasting. Man that's like the main PvP Talent for Druids. I gotta hand it to you, you do have Furor, it's quite impresive since ur other damn talents u added are pretty much useless in PvP. And you do have Naturalist Shapeshifter and Master Shapeshifter. That's good. And you have Intensity ( altho you still need Dreamstate, trust me! ). And you have Omen of Clarity thats both bad and good, depending of how much ur crit chance is. And by now you probably realised that if u'll use the specc i suggest you, you will still have some talents left. Use them wisely altho I VERY MUCH SUGGEST Glyph of Insect Swarm + Glyph of Moonfire and add some damn talents in Improved Moonfire. Btw you did good that you didnt add talents in Owlkin Frenzy, useless in both PvP and PvE ( if u have Nature's Reach Talent that is.. )
I wait your answer in 10 minutes
Hope i helped
