The standalone client launcher is broken since month, the only way to play bugframe is via the steam client but steam hangs in a "searching for updates, trying later loop".
Nice job DE!
The unique way I see, for free ammo pots, is to use proteas "1st (apothecary (helminth exchange))" to change any ability of the warframe you use in the mission.
Who the hell thinks about this if you don't want to change your best damage abilities?
Its the riven disposition. Unequipped riven has nice stats, when equipped you're dissapointed about :o)
check out this and take notice about the circles at the beginning of the table.

And me as well..
I was in an Archon Hunt at the last boss. I used weapons which use ammo. A few minutes later the entire group ran out out ammo. No ammo drops nowhere and you cant drop ammo pots. We had to hack and slash for about 25min the last boss.
Since this experience, I don't equip weapons at Archon Hunt missions they need ammo.
