stage one: car
you have your starter car not enough parts to do anything so you use car.
stage two: smol box
you have parts but not the skill to build with them, so you make a box and put guns and wheels on it.
Stage three: armored car
Skill building is starting to catch up with parts, your build start to look more like combat vehicles.
Stage four: TANK/ FAV
You know what you are doing, you have the skill to build it and the knowledge to use it, be it a fast moving hover, a hit and run shotgun, or even a cannon miller or tank that can take every shot in existance.
Stage five: DEATHMACHINE
Your skill has grown even more you know how to combo cabs, modules, and weapons to maximize DPS or DPH, you can make do with almost any weapon in the game to make a vehicle of pure destruction nomater the type.
Stage SIX A: BOX
This stage is rare, you made the mistake of wanting a relic, and had to play the meta, all creativity is gone you are a box with hovers and spaced armor, for if you are anything else you loose, no more interesting part combos, no more redusing your DPS to help your team, or adding a utility tool to do something cool, you are now box, and you must remain box until you get your relic, but by the time you get said relic you forgot how to play not box.
everyone hates the box, even teh box players.
Stage SIX B: SPACE BS
How are you flying in a mad max game? This is the alt on the other side instead of going meta and working for a relic you have settled in and now it is time to experement you find the interesting combos, and help shape the meta the box users use, sadly though msot see you as doing space magic that makes no sense. Good news the rep that comes with this is grand bad news, you now have to pay to keep up with parts to keep this rank or go back to stage five.
