Considering the recent thread discussions about the Blitz's lackluster performance and nearly unanimous votes on buffing it, I felt my thoughts were getting too specific so I'd like to just make those suggestions separately and see what people think.
I believe that the current build for the Blitz has good building blocks, but doesn't fit the dragon into a support class/crowd control niche well at all. Its low range and health limit its ability to do damage at all without risking being one-shot, despite its high DPS; its less a glass cannon and more a glass shotgun - up against a sniper and two other actual shotguns, not to mention the steamroller that is the Spitter. That combined with the stun immunity a dragon gets even if it IS hit by a Strike means you really only need one, maybe two Blitz in a fight, because there are otherwise significantly better combat choices for the remainder of your party.
I think some relatively minor number changes could fit Blitz into a supporting crowd controller better. This is assuming that the maximum speed of a Blitz stays how it is currently due to Bio needing to be able to escape, and that the stun immunity, charge times and all stats other than the discussed stay the same for the Blitz and its attacks.
I don't think Blitz needs to do as much damage as it does if it's supposed to be a support class, so I think that could easily be traded out for more stunning capability. Medium damage, but longer range for the bile attack. Now, the Blitz Strike doesn't have much range either, and I think it could also be increased, but only by like, another 1/2 to 3/4ths of its body length, because you don't want to also stun your own crew in a fight. It can also do reduced damage, trading for either significantly faster bile recharge (because you still have to wait about 15 seconds for it to start recharging when you Strike), or just removing the wait time before starting to recharge, whichever is more feasible in coding.
