Notice: I've had to temporarily abandon all my projects as I no longer have a running subscription, and I have to make a living. I'm working a summer job in northwestern Ontario which has no internet access, so don't have the option to work on WoW-related things. Sorry. If you would like to pick up this project, send me a private message and I will try to get back to you ASAP. All you would really need to do is convert Simulationcraft APLs to table-object-oriented Lua, but it would be nice to see some code performance enhancements as well.

Basic Resources has a separate command from Smash, it is /bres - not /smash! (commands are separate incase people want to lock or scale one but not the other, or want to run just Basic Resources or just Smash)

Smash is an addon for warriors that simplifies gameplay and maximizes DPS by doing all the decision making for you.
Unlike some other addons, Smash uses an advanced priority list developed by the people over at the SimulationCraft project and improved by myself for ease of use in actual gameplay.
It will calculate which ability would give you the highest DPS during the current combat situation.

The addon is comprised of three icons, left to right they are:

The Previously Used Ability icon - Displays the last correct ability you used (to show you that you actually used it before the icon changed, can be disabled)
The Best Choice Ability icon - Displays the best ability to use for maximum DPS during the current combat situation
The Cooldown Ability icon - Displays when you should use an ability that is off the global cooldown or has a long cooldown (can be disabled)

Other features of Smash includes:

Glowing Ability Buttons - Your ability buttons glow when they become the best choice ability
Multi-Target Modes - Use keybindings or clicks to switch between single target and 2, 3, or 4+ target modes
Know When You Miss - A red border will appear on the previously used icon when your attack misses or gets parried or dodged
Moveable, Lockable, and Scalable - Each icon can separately be moved to wherever you like on the screen, then locked or scaled to any size
Resource Bars AddOn - No dependencies! Must be enabled within the AddOns menu on the character selection screen

Slash command for Smash user configurable options: /smash

Basic Resources is an included optional addon that displays vital information such as your rage, buff stacks, and global cooldown in a simple and elegant fashion.
It also works on other classes and has additional useful or annoying features.

Slash command for Basic Resources user configurable options: /bres and /cres

F.A.Q.

Why is it called Smash?
ORC SMASH!!!!!!!!!!!!!!!!!
Where is it? I don't see it!
Both addons hide themselves when you aren't targetting something you're able to attack. Try selecting a training dummy to move it around and such.
How do I bind keys to change the amount of enemies?
Look in Game Menu -> Key Bindings -> Other for Smash, you can set bindings there.
Can I hide for a specific spec?
You can use /smash hidespec 1 to hide in primary or /smash hidespec 2 to hide in secondary spec.
Is there a way to turn the rotation helper off? I only want the rage/gcd/buff stack bars.
As stated above, the resource addon is standalone (no dependencies). Just disable Smash on the addons screen and keep Basic Resources on.
Why does it take up so much RAM?
Why are you playing WoW on an Atari! I've never measured it above 120 kB.
Can I get this addon for other classes?
Look up Claw if you play a druid. Shrapnel if you play a hunter.
