The problem is that it's easier to shoot 1 of 2 weaker projectiles and survive than hit 1 or got your ass handed. It's do or die.
Make Resheph fire 2 weaker projectiles instead of 1 would solve it.
I think that would just make it an Akula clone though.
Not really, since Akula is an exclusive unit for Russia while Resheph is available to everyone.
