Klepto is the suggested vice, you choose it when making a commander.

so how do i set a scenerio to be klepto or whatever it is I am suppoed to do to get one of these RNG jetpacks?

huh i didn't know this was a thing. jetpack is so mindblowingly insane as an upgrade, i would intentionally spec into range klepto just to get jetpack. then again, there are alot of issues with mods/weapons availability.

i.e. why does a random hero sometimes spawn with a final research tier weapon and one of the best mods in the game?

I didn't even know this was an issue; I always get jetpacks.

There were a few drones (even when they didn't always fit the theme of the hero or race). Once per fight support buffs were very common, and there were a few race specific passive items.

You might be surprised to know that secret tech specific loadouts have no variability at all.
Melee classes often get 'exoskeleton system' which increases map movement and gives +1 ranged defense, my opinion is that exoskeleton isn't all that good so I swapped it for displacement system.

Ranged secret tech loadouts always got jetpack which was nice, but sharpshooter didn't even have jetpack in the table.

I tried to go for a soft 'best case scenario' kind of thing. That would stop my friends and I getting jealous over each other's klepto rolls, and discourage constant rerolling/restarting games when playing solo.

What was the old table like? I only did Klepto a few times because it was so random, and I'mcurious...
