I pull 4 targets and I have 4 groups. then I use this hotkey. /multiline ; /noparse /notify ExtendedTargetWnd ETW_Gauge0 leftmouseup;/assistme /only|Tank1 /multiline ; /noparse /notify ExtendedTargetWnd ETW_Gauge1 leftmouseup;/assistme /only|Tank2 /multiline ; /noparse /notify ExtendedTargetWnd ETW_Gauge2 leftmouseup;/assistme /only|Tank3 /multiline ; /noparse /notify ExtendedTargetWnd ETW_Gauge3 leftmouseup;/assistme /only|Tank4 /multiline ; /timed 40 /bct Tank1 //assistme /only|group;/timed 40 /bct Tank2 //assistme /only|group;/timed 40 /bct Tank3 //assistme /only|group;/timed 40 /bct Tank4 //assistme /only|group; replace Tank1 with the name of your Tank in your first group, Tank2 with the name of your tank in your second group, etc. first 4 lines has each tank engage a separate mob that shows up on Extended Target Window (the first 4) last line has all tanks have their groups assist them after 4 seconds. Each group gets experience when the mobs die. be sure to have Eyes Wide Open AA (no cost) You can group up the lines (probably 3 to 4 tanks per line) for those that have more groups, so this could support 15 or more groups on one command. though I think the ETW only has 13 maximum. customize it/use it as you see fit.
