Well I'm leveling up a Jedi guardian and have an ability that is more or less my "basic attack" called Sundering strike only problem is it has a 4 second cd so every now and then when I'm ready to use it in my rotation it is still on CD because I'm leveling i only have so many abilitys.
I have a mouse that allows me to use macros so I have it set up so that i can use Both my basic attack and sundering strike with one button press depending on CD but this creates an error message that pops up it can be ignored but i would prefer just to not see it.
