Go for 25% haste, once you add in your own 15% it becomes the dominate driver for your damage.
Also I'm assuming the 35 enspell is from a sh!tty enspell 2. Use enspell 1 instead, at two hits per round minimum (DW) and the amount of DA you can rock, enspell 1 pretty much destroys 2. Sitting at 496 enhancing magic until I can get my +2 body +2 hands and augmented A.head. That makes 29 damage enspell per hit and 19% DA (assuming I haven't hit the unknown cap yet).
My gear is,
Z.tiara
Twilight Torque (or Rancor Collar if I'm not worried about heavy damage intake)
Suppa
Brutal
ACP Body +10 Atk +10 Acc
Brego Gloves
Rajas Ring
Keen Ring
Atheling
Speed Belt
Calmaic Pants
Erudos Boots (spelling)
That puts me a little under haste cap and 10% DA from gear 2% TA. When combined with Temper your looking at 29% DA and 2% TA.
Also something I keep noticing is the sheer amount of accuracy everyone seems to want to add. Accuracy hasn't been an issue since we left the level 80 cap due to how the skills have scaled. Now this isn't to say that SE wont' introduce some crazy new sets of highly evasive monsters, but for the immediate future I'm using Bison Steaks. I'll post WS set later.
