When to stop gathering haste?

Oath gives spellpower bonus to the shaman that procs it.

Anyhow, stats isn't everything, biggest factor is lag and playstyle in dps.

There is only one way to play, to maximize your dps, there is no playstyles per se.
And stats are 90% of Your dps, then comes skill. Anything above 200ms will make You suck vs other shamans in same gear.
Also 99% of the shamans that I meet are bad, bad specs, bad gearing, bad rotations, just the other day I meet a shaman that stacked spirirt, or one that only used LB...or one that still specced into resto, that's all within 2 days :P
