UPDATE June 27, 2014: Katarns can now go up to Tier 5!!! Now it's worth stocking up on Katarns to have your own team of fearsome lizards!
Katarn, like the Watch-Beast, Advozse, Duros and Jawa, is faster to level up than IG-88 and R2-D2 (and way faster than Spider and Terentatek) because he requires less XP than them, so you would think that Katarns are normal like Anzat, Shistavanen, C-3PO and Sakiyan. However, there is either a brand new category of XP requirements, or there was a recent change in the game that makes all normal characters slower to level up. You know those guys at LucasArts -- always keeping us on our toes by introducing random changes!
