Missile frigates are broken

Spamming missile frigates absolutely breaks the game. So far I've played 20+ games as Vasari Exodus and managed to effortlessly raze my way to the enemy capital worlds and wipe them off the map with a fleet composition made up entirely of kanraks. Same holds true for other factions but considering how innately aggressive the Exodus faction is, it's ridiculously hard to counter this particular tactic unless your enemy scouts you early and dedicates his build to maximizing PD defense. Missile frigates require a nerf or PD counters need to be seriously rebalanced to improve efficacy against missile frigates en masse (perhaps a research tree upgrade improving their role againts missiles at the cost of lower attack against strikecraft?). Regardless of whatever fix is decided on, the current state of missile frigates is too broken to make the game much fun anymore lol.
