Yes, they way you are explaining it we will have people sitting on the external gates with hardened shields.
Sure they can be "shot" for a second or two, but when the jump back in though the external gate, they can wait out there protection (all the while getting ACC) and then just jump right back until there flag runs out. With next to zero risk of dieing.
The reason you cant do it now is that you cant jump on externals. If you do this, you need to add in, either if you are flagged you have ZERO protection when jumping, OR you instantly reflag AND your protection is Halfed.
As it is right now YOU CAN jump back in forth through externals gates with next to no chance of getting killed. There is a chance but you have to get really lucky to get them. And if they are shielded...just forget it. You will never neut them with a ictus and kill them intime before they jump back and forth.
