Honestly, I feel like that's actually a good thing. The premium warbonds should focus on fun new toys, but nothing that you need to have in order to have fun and succeed at missions.
the grenade pistol would make most blitz really efficient though, probably most easy to get the "Hold my primary" achievement by getting that and join a blitz group trying to unlock that. )
Of course, it's more of a personal preference thing, I like a lot of the stuff in the laser warbond, while a dude I play with is very stoked for what's in this new one, just different strokes
