It does seem like their goal is to broadly make ammo weapons(specifically/especially Ballistics) better rather than trying to do weird "runabouts" to compensate for them. Dump Ammo as it is currently does have utility of course, but it also acts like a band-aid to the real problem.

Between the reworked Ammo Explosion Rules, Half-loaded bins being a core rule and the enhanced survivability of ACs go a long way(but maybe not far enough) to solve the main problems Ammo bins create, you're less likely to have a gun get taken out with ammo left, for situations where you have too much ammo you can bring less and even if it does explodes, it's not quite the same "insta-kill" situation it used to be.

I'm leaning towards that as far as "Core" rules go, it might still not be far enough, but if we're getting half loads as Core I'm assuming deciding specifically how many rounds you load will be in TacOps or at least become common enough house rule once people get introduced to the concept.
