Hey, I'm looking for help or an addon that is configurable to set up a DPS rotation. If anyone has heard of Facesmasher (http://wow.curse.com/downloads/wow-addons/details/face-smasher.aspx) If someone could point me toward some script ideas or way to make this possible with other classes, it'd be more than appreciated.

The idea is:

I just engaged a mob, everything is up and no CD. The first thing I should do is White attack the mob to generate rage (The auto attack Icon should be showing in icon 1.) I strike the mob generating 60 rage. If my rage is >25 and WW is not on CD, WW should be next icon after auto attack icon; However is WW is on CD, but BT is not, BT should be the next icon. If both are on CD, and BT has 1.7 seconds left before coming off CD the next icon should be HS, followed by BT.

I know it seems a bit confusing, but just hear me out. I think if someone shows me a way to check if an ability is on CD, how much rage I have available and if certain buffs (SLAM!) are active, I can finish the rest myself.

You can't check whether an ability is on cooldown and choose an ability based on that in any automatic way.  That's something that Blizzard has specifically prevented.  You also can't check mana/energy/rage levels and choose one, or whether buffs are on and choose one.  Attempting to do so anyway is a terms of service violation.

These things used to be possible; Blizzard specifically chose to make them no longer possible.

The idea isn't to choose or to automatically use an ability. It's just to show the Icon of the next ability. I don't want 1 button does all, I just want to know if I need to refresh Rend before I MS again, and something of that sort.

Ah, I see.  

Rage is treated as a type of mana for the system, so UnitMana("player") will return a warrior's rage level.  

GetSpellCooldown() returns cooldown information, UnitBuff() can get buff information, and GetSpellInfo() can give you the icon for an ability.  All of those have a slew of return values, though, so I'd suggest looking them up on WoWwiki to see how to use them.

I used Tellmewhen awhile ago and it does exactly that. It requires some setup but works for any class including buffs/debuffs cooldowns etc, if u got omnicc it also shows a timer.
