I'm saying this:
if you're inside an f18 and you want to fire a sidewinder to your ugly-bad-iraqi enemy, you have to push a button on the control stick
You could be the best pilot of the entire U.S. Air Force, with a great ability in combat and with an high precision in firing sidewinders, but if you don't press that button you cannot fire the missile
In the same way I don't think a jock could "activate" a weapon only 'cause he/she has got the ability related to that weapon; he/she is inside a cockpit and probably he/she activates weapons using some controls inside the cockpit.
So the abilities related to the different kind of weapons determine jock's firing-precision, but the action of "FIRING" the weapons is a much more complex issue.
One of your arguments against my idea is that an infected titan could not fire its weapons 'cause the jock of the attacker titan cannot control its weapons.
And you affirm this thing 'cause you say that those weapons are controlled by weapons' abilities of the jock inside the infected titan.
So I'm continuing to think that you probably didn't catch well my idea.
The weapons installed on a titan are controlled by the jock who "activates" them ("the one who pushes the button").
In particular, on medium, heavy and assault titans, the controls are part manual and part neural ('cause of the neural bridge device).
If a titan is infected by nanos, it's the jock of the attacker titan who can control the infected one in some cases.
So he/she can "push the button" instead of the jock of the infected titan, using his/her own abilities to fire the weapons.
I'm not saying that the neural-sense is a weapons' ability; I'm saying that weapons' abilities determine the firing-precision with the different kind of weapons, but they have nothing to do with the "activation" of the weapons, which is certainly due to some kind of controls.
This is my point of wiew, and maybe it's wrong, but I have some doubts about yours.
About the EMP:
I'm not saying that the new weapon will surely unbalance the races. I hope it won't.
But I think that the concept of that weapon has got more consequences than the ones you discussed about on this forum.
