My feedback:
I'd remove 1 red die from the rear arc and give it an additional blue die to its front arc, as 2 red dice from its front arc is rather weak for a ship known to boast firepower heavier than its class. I'd also be tempted to give it only 4 hull (I wish they had a bit more spread between the hull values, as a 150 meter Raider having only 1 less hullpoint than a 500 meter Gladiator makes so little sense) as its less massive than the Gladiator and is known for its structural weakness due to the ship consisting of several attached premade modular parts, in which case it would warrant a price reduction as atm it is just as expensive as a Gladiator-II for 2 less overall firepower, 1 less anti squadron die and no Brace, while in exchange it only has 1 extra shield, 1 extra click at speed 2 and an extra redirect.
It does have firepower heavier than its class, though: it has the exact same number of dice as an AFMk2, only losing a little range on the broadsides. The GSD has more dice, but much shorter range, which severely limits its value (compare the cost of a CR90A and a CR90B). I could always shift dice around without changing the overall count, but I also don't want to make double-arc shots completely devastating.
As for the hull, I considered going down to 4 but instead decided to just not give it a Brace (let alone Contain), which makes it substantially weaker once the shields are down and the Redirects become useless. It's both longer and bulkier than a Nebulon, so less than 5 would feel weird.
Perhaps adding redundant upgrade slots (Offensive and Defensive? or Offensive and Turbolaser?) will make it feel more "modular" and better value for points?
The hull points are funny. FFG made the MC30c a 4 hullpoint ship (without brace) even though its nearly 600 meters long. It's my belief they should have used a larger scale (i.e. lower end corvettes 2 or 3 hull points, upper end ISD's 14 or 15 hull points) so there is more room for different hullpoints on different ships.
In any case, I'd liked to have seen the Strike-class as a (somewhat weaker and therefor cheaper) Imperial mirror to the MC30c (so weak hull, potent shields), but with a long or mid range focus rather than a short range. Atm if you compare the two, sure the MC30c is a couple points more expensive but I'd pick it any day over the Strike-class. Changing a rear die to a front die is just preference I suppose, but to me it just strikes as odd to have an Imperial ship with as much rear firepower as forward firepower, and it would give it a bit of an extra bite.
