yes, but does he have the back door? and it obviously has that gaping hole in the back where the 'cannon' should go pointing out that you have done this.
but seriously, i believe that the Stormfang is just inferior to the Stormwolf in every way but appearance of the destructor is kind of cool. what it loses from the differences between the Stormwolf and the stormfang is quite significant. 10 model capacity, Assault ramp, Las Cannons, a turretted
twin-linked helfrost cannon. In return you get the 2, one use only stormstrike missiles (in place of the las cannons, which you can regain for another 15 points back onto the model) and the destructor, which has the same range, and almost the same power as the helfrost cannon (the blast is 1 ap better, and has a large blast template, where the single target attack only gains the Lance ability) AND it costs a little MORE base cost then the Stormwolf, while taking up a heavy support choice, which in all arguements is better spent on other things (long fangs, LRC, LRR if you like flamers) where the stormwolf can be taken as a DT for a full compliment of Bloodclaws with ulric.
