No one can tell me how much enh shaman needs hit rating and expertise at PvP? It's simple question i think, help me.

Personally if I were you, I would not use grim toll. I would keep using those 2 trinkets and try gemming for Armor Pen in your red sockets instead. You already have a lot from gear. A lot depends on your guild though and if you find yourself on single target boss duty most of the time or not.

Been reading bits and pieces of the thread and was just curious if my gem choices were okay or not. If you look in my armory page you'll notice I gem for +20 haste in just about every spot I can get. Now every other warlock I've seen has either went 23 SP or SP/Haste and a few gem for SP/Spirit (even more than 2 total blue gems).

I'm just curious if I should regem to SP/Haste and SP/Spirit to match the socket bonuses in all my pieces or pure 23 SP and ignore socket bonuses or just stay the way I am. I currently do 5500-6000 DPS on average in a 25 man, with short fights or standing still fights like VoA bosses I can do 6200 (flasked and everything).

Also one more question if you check my armory again I'm using Deathchill Cloak and wondering if the new Volde's Cloak of the Night Sky is a decent replacement or if I should wait for T10 pieces. The cloak itself doesn't look to great but compared to my current cloak it is a massive upgrade~.

I would just spreadsheet my stuff but I can't get the spreadsheet to work from the warlock spreadsheet thread :<.

You need 5% hit against player characters (not shaman specific.)
There is no expertise number as it would vary wildly between hitting a mage and hitting a rogue.

For more information you could check out the Arena Junkies Shaman FAQ.

Like falling damage, it doesn't show, right? How about drowning?
Is combat log bugged too, along with the trinket and soul link?

@Tukuto
I would use [Justicebringer] and [Reckoning]. You should be able to hit 5% (164 hit rating) with other gear very easily.

I would put [Ramaladni's Blade of Culling] in the MH (more weapon damage) and [Dual-blade Butcher] in the OH.

Even with the speed being faster?

It has higher damage, and while it doesnt matter THAT much, slam scales with weapon damage so even though its faster, its a better main hand.

Nibelung . Just curious how this staff fares compared to an Weapon and an offhand

I don't think it is asinine, since we are discussing game mechanics. Life Tap not being "damage" in that sense explains why it doesnt show in the log and is not affected by soul link. Whether this is by design and trinket is bugged, or three other things are and trinket is fine, is a guess based on probability
