What is GupSlamAlert:
GupSlamAlert is a small AddOn that plays a sound and displays a message when a warrior receives the instant Slam! buff. It also has support for the T10 set bonus with a different sound.
The addon is based on the SlamAlert but since 3.3 this addon was broken cuz blizzard changed something (Should work again in the latest patch). GupSlamAlert is a complete rewrite of it with a more improved code.
/gsa or /GupSlamAlert to open the optionmenu
Added a check if you get the buff with 2 stacks by the t10 setbonus.
Fixed a bug that causes a error on boot duo copy and paste from GupPet
