Any good ways to get Cryo/Incendiary Ammo (MP)?

I wish we could buy them in the item store for 5-20 mission funds depending on quality. I also need them for my huntress to increase her normally low damage output in platinum w/o a primer for throw.

yeah pretty much why i'm chasing them.   I really don't want to have to play another class other than the one i like (duelist) in golds.  I play that class quite well, but to really make it viable then either incendiary or cryo ammo is very useful.  

I would love an ammo crate of random ammunition types.. or even the option to buy the exact type i want, but i'd be happy even for random.  There comes a point where you've just got way too much of everything else and its these ammo types that are the only thing you are waiting for.

I have many hundreds of RPGs, ammo reloads, etc, which I will never use up, all because I buy jumbo packs just to get some ammo modifiers.  ...annoying for sure.  Two golds completed so do I spend the 100k funds with a chance to level up something I care about?  Or do I want to buy 10 jumbo packs to get a few ammo modifiers.  ...feels bad man

But I expect Bioware knows and is doing this as a sink to suck up your valuable funds and slow down your ability to level your weapons and characters, which theoretically will give you incentive to keep playing longer.  I'm not so sure.  To me it's an incentive to avoid the characters that are the most fun.

Well considering the 1300+ card grind we've got, they should probably think about helping us to enjoy that grind, not hamper it at every junction.

I doubt they sink the same hours many of us do into this game, so they've no idea the of the nature of the grind they've set before us, and i don't think for a second that giving us a better supply of boosters especially for ammo will harm one bit.

Playing without ammo boosters in the way i play makes the combat feel very dull at least if i can prime up with my weapon i stand some chance of surviving.

Play better?  ha.. if you could see how i play you'd know that i play a very quick twitch reaction game, and there is only so much you can do in some firefights, so having the elemental ammo really helps, but it does not make it too easy, you still have to really fight your way out.
