At present, the pink lootboxes give fairly frequent rewards of all three 'Speedy Hoppers' and a Refined Storage 'Speed Upgrade'. This likely encourages players to use these items (because free stuff!), which in turn can impact tick-speed - both on servers and in single-player builds.

Suggest replacing or balancing the hoppers with either cheap servos or itemducts and the RS 'Speed Upgrade' with some low-grade AE2 reward.
