Running the new Christmas missions and killing the champions on two characters, I noticed a distinct difference in the loot they received from the bags.
My main (way past 1k IP) got showered with gadgets, most of them mythic and legendary. Worst loot was a purple Electrogravitic Attractor and one green bag with trees.
My alt (barely E8) only got blue distillates in the 1.2-1.4k range and green bags with decoration items.
Statistical fluke or pattern ?
