Been playing for a while and after opening 100 premium packs throughout my time playing I decided to make a list showing how common each premium item and arranging them from most common to the most rare
I will not count legendary items that you can get at epic rarity
I will also assume that item type (energy or heat) won't affect the drop rates
And lastly I will put each item in their category (legs,side weapons etc) and how many I got
Please note this based on my personal experience so the results might be different from one person to another

1-Sparked Runners/Rolling Beasts (Most common Legs and most common premium items)
