The Shaman build I am currently using is the 51 shaman 15 druid. (0 point sentinel for the heal)
The 15 I put in druid are:
5 Guiding hand = +5% damage.
5 Mercurial = +10% damage on instant casts.
5 Brutal Impact= +10% physical damage ... This could be easily put into the INQUISITOR for spell power.
Now why this is the Lazy Build... The main macro is:
cast Rage of the North
cast Frozen Wrath
cast Massive Blow
cast Rush of Strength
cast Combined Effort
cast Icy Blow
cast Ekkehard's Grasp
Lighting hammer is applied separately.
The only DPS loss is up front when rush of strength triggers (without being needed) and jolt may go off once without being under a crit. After that initial loss it is just click the macro and refresh lightening hammer when it falls off.
So far the actual damage is so close to using the non-phys and phys macros that it often out-parses the two button macro setup due to just clicking one macro.
Give it a shot. Especially if your lazy !
