It would be awesome to get one-time use items like XP Boosters, Credit Boosters, etc.
These would fit outside of the realm of the gear/mods. While gear/mods are generally applied as methods to tweak your playstyle and characters - Boosters could be one-time items that are consumed and grant a boost for the next match you play. These boosters would not affect your character’s strength, but only assist your own end match xp gain, credits received, etc.
Players could receive boosters randomly through play, in gear boxes, shift codes, or even purchasing through the store. Boosters could have multiplied effects during events like the XP event recently.
Just a thought as another way to tweak progression and another bit of loot to look forward to using - what do you think?
