Alright so here is the issue that i'm trying to fix. I would like to make a macro that switches my 2H to my 1H and shield, and then cast shield bash; then if shield bash is on CD switch back to my 2H all in one button. I had a macro working with inventory switchs but when you switch from your 1H shield back to your 2H it places your shield in the last empty slot and loosing the slots position in the macro. /eq and /equip doesn't work; any help would be appreciated. Thanks.
