So its that time again, new patch, new toys, new ways of blowing stuff up. I'm going to talk about DPS rotation theory here, I'm not going to be writing macros - you should all know how to do that by now.

So your general rotation is FS, LvB, CL, LB. This has been a static rotation for some time now. However, we need to do a dynamic priority based rotation, as different abilities have different cooldowns and durations.

Shaman have two different DPS phases.

Phase 1 - Prioritized Cooldown abilities
1) Flame Shock
2) Lava Burst
3) Chain Lightning

These are abilities that you use in a priority order, as I have listed above (in that order).

Phase 2 - Spam!
4) Lightning bolt

When everything else is on cooldown, this is what you should be doing.

Now, the biggest change is elemental mastery. It now provides HASTE for the duration. This is a significant change.

Before we also used to macro in EM with LvB, to get the instant cast on LvB. This is most likely not what we should be doing anymore. I have moved mine down to CL, so CL is instant, and when entering Phase 2 of the DPS rotation, the haste duration is used only to boost LB (more LB casts before Phase 1).

This also holds true for HASTE "use" trinkets and engineering buffs (hyper speed accelerators). If you've got them, use them for your LB phase, NOT for your FS - LvB - CL phases. Obviously there will be some overlap, but the idea is to prioritize your haste abilities and items towards your LB phase. You should also "attempt" to blow heroism/bloodlust as your entering Phase 2 - although this is less important overall, because Heroism/Bloodlust has a much longer duration.

Also, you should all have your Tier 9 two-piece bonus by now - don't forget to adjust your flame shock macros.
