Well, Nipsu,
All the answers you want are in this thread but for the sake of helping a new arrival through 30 pages:
- Getting hit capped (or very close) is indeed of key importance. There are several options for us, but a combination of the gunship neck, mittens, T10 pieces and the icc-rep ring should get you there while using some gems
- for regular gem choices, the logic is to use either Runed or Reckless (depending on socket colour). Use Runed for blue slots except the 2 you ned to get your meta working
- recently it has been found that if you are very close to 1115 haste without relic and have 4 T10, you may want to gem Reckless in red slots to reach this, so you can make use of a small dps increase using EM in combi with FlS. It's tricky to use it though
- It has been found that 4xT10 outweighs 2xT10 + 2 nonset (at 264 or 277 lvl). The weakest T10 pieces are the gloves or the legs (which is why these are the only ones dropping from VoA). Since you cant get the proper offset legs, I advise mittens + T10 legs, and all other pieces also T10. The helmet you use is a big dps decrease; change it asap to T10
- CL usage is controversial; there is a small dps increase involved also on single target, but it eats mana. Some players use it to get their next LvB better aligned with the 8sec CD and fill the rest with LB. I would suggest you just try it out what works well for you
- In general I recommend to download ZAP or similar to see what glyphs and stats produce the best dps gains, so you can evaluate gear etc better. Currently however, Lightning Bolt and Totem of Wrath are top, closely followed by Flametongue and Lava. Whether you prefer Flametongue or Lava is a bit of a personal choice since the differences between them appear very small. Please check for your gearlevel if this is true
Good luck with your new role
Edit: I assume you can get access to 264 tokens at Saurfang. 251 lvl T10 is not up to par with 264 non-set items
