Like I said the rail build is almost on parity right now as it is.. there are quite a lot who run it that it's almost meta. if you reduce the TC effect you'd have to be very careful to not go too far, I'd be ok with a sliding scale but would need careful balancing. It's an art to manage heat with TC as it is. You would absolutely just be making a rail spam meta if you reduce the effect of TC too much.i am afraid not as long as the heat system is not reworked and i dont see this coming shortly. one has no problem to constantly overheat his ship to get the 60% buff on every volley without having problematic penalties at all.
so imho the damage increase has to be changed as well.
