I'd make sure to drop ToW on every toon, even if your totem macro will drop different fire totems.
The extra spell damage is very worthwhile.

I like your glyph choices, although the Lightning isn't huge, after Lava and ToW glyphs, there aren't any that stand out as much better then the others.



As far as timing your macro's.
You need to adjust for your own personal clicking speed.
One way to do this, is to physically move the other three macro's off of their button slots.
So for example, only Flame Shock macro is in place to be called.
See if you refresh it, just as it expires.
Add comma's if its up still when it refreshes.
Remove comma's if there's a delay.

Once Flame Shock is fine, do the same with Lava Burst.

You won't actually have to adjust the timing on the Lightning Bolt, as it is the fall through.
But you should verify that is actually does cast.



As far as heroics go, you only need 80's or 90's (relatively low amount), when combined with all of the hit talents available, especially if you're a Draenei.

In heroic content, if your toons are raid hit-capped, then you are wasting a very large amount of itemization. For raids, you need a lot more hit, to reach cap. Until you're hit capped for the content you're doing, that's the best bang for your buck. Once you are capped for the content you're doing, spell power is the most beneficial stat, but crit is good too.

Mana per 5 will help sustained dps, but won't do anything for short term dps.

I personally prioritize Hit (until capped for content) > Spell Power > Crit > MP5 > Haste.



Talents will differ depending on how much you pvp or not.

However, I don't see any for PvE content which you should have but don't.

I really like faster Grounding totems, but that doesn't impact your DPS a whole lot.
