I'm just curious but how is this fire mode any different from hold fire + click to shoot?
It does have that nice loading ammo bar otherwise its no different.
(which would be cool if we could activate it on all units without the special fire mode)
This mode allows you to shoot the guy of your choosing not jus right click and and a random guy gets shot. So lets say a certain guy has a weapon (shrek/zook) and you can click on that guy and he gets killed, either dropping the weapon or it getting switched. But everytime you av a certain chance to make that squad drop the weapon. Which could be really useful in split second situations.
EDIT:
only usefullness of this would be that it's easier for u to countersnipe or kill officers, but that's it.
this whole ToV direct fire was a fail. it only works on tigers... a bit. since u can actually tell the tiger to shoot on the blobbed part of the 6 man squad instead of on the lonely guy.
so if u wanna add it, add it to the tiger ace.
You should check out the blitzkrieg mod. Most of the tanks av this option to go into direct fire mode (plus sniper) and its amazing. You get to aim your turrent at a certain point before you go round and get the first shot off. But im not suggesting it for tanks but the sniper.
