if he would be tank, i'd say thats ok. cos assassins are only tanks that can tank in range, shock and discharge have aggro-modificators on them, force lightning immune to pushback.
I'm most concerned about rapidshot, powertech free-skill. U can watch it in logs:

it's really strange, but it shows that rapidshots generates aggro from x5 to x15
whats ur thoughts?
