Here is just some of the few of many things i noticed from glancing over it for about 45 seconds:
1 -WF/WF, Totally wrong, they share ICD. WF/FB does more damage on PvP Targets (Since the FB 10% damage proc doesn't effect training dummys) plus has more utility, i can go more in depth with this, but im too lazy.
2 -I noticed you were using a battlemaster trinket, Wrong. that's like a mage using an attack power trinket.
3 -Rotation? Who the **** uses rotation in a PvP environment.
4 -Spell pen optional?? No never EVER EVER EVER EVER!. Spell pen is a MUST, MUST MUST MUST. Without it 90% of your shears/purges will be resisted (Guaranteed!), and enh's damage is 50% nature (Shocks, Lightning bolts, FB Procs, Lava Lash), meaning half of your damage will get reduced.
5 -Your enchant on your screen shot, +65 attack power, Who in the world.....Eh ima just stop.
And this is just the few things i noticed from just glancing over it, Please don't make me actually look through it to list all of them.
