So I earned the max crate today and absolutely enjoyed the mode and the various challenges. My feedback for normal echoes much of what already has been said, but here is another data point for the collection.
1. I would suggest lowering the energy cost per attempt to 12 instead of 15. This gives players 12 initial attempts at the mode which may become more important for those doing hard difficultly. Another reason is that every other energy node in the game costs an even amount of energy and it would be nice to keep the consistency.
2. Jawa Scavenger. Other players have noted that scrolling through the wall of gear options is a bit tedious to which I agree, additionally, once you have unlocked one gear scavenger there is little reason to unlock another since they currently share the same gear. Maybe make the Scavenger in each sector have a different selection of gear with Sector 1 having Mk.3 Carbanti's/Holoprojectors, Sector 2 MK. 5 Stun Guns/Cuffs/Droid Callers, Sector 3 starts G12 gear, and so on. This opens up more options for players and clears up the store a little bit.
3. The "milestone" rewards that you can gain on your way to boxes could use a little tweaking. Maybe add some mod slicing mats, signal data, 5 pieces of gear salvage to each milestone. The currency is definitely rewarding, but 100k of each credit type is not as beneficial as other things to players later in the game.
