First of all, I'll actually argue that the planatary turbolaser is actually too powerful at the moment. It essentially neutralizes all cruiser class ships and even some destroyers in a single shot, and it's recharge is short enough that it can be fired 3-4 times during a long engagement. One particular instance comes to mind where I destroyed a Venator-I in a single shot. For it's price (don't really remember, but it's not over 15k), it's extremely effective, seeing as a Venator costs basically 10k minimum (Being built at Kuat). Something that costs 15k should not be able to destroy a ship worth 10k 3-4 times per battle.
Second, is there a random damage roll on how much the turbolaser does? As mentioned above, I once destroyed a Venator-I from full shields/health in a single shot, but when I fired it at another Venator later in the same battle, it just crippled it, taking out its shield and bringing it down to about 10-15% health.
Edit: In that vein of thought, I think the energy weapon on the Venator-II is a tad stronger than it should be as well. First, it has incredible range (On the scale of a heavy turbolaser) and does amazing damage. My 4 Venator-II's destroyed a Golan 2 in a single volley.
