I thought of this in the middle of my Monday Meth Orgy.
Stage 1: Small and random horde without a dominant colour scheme. Often includes your coolest looking figs and some beginner vehicles(mostly functionality over design).
E.g. Any Merc force.
Stage 2: Small force with colour scheme and improved vehicles that fit the colour scheme. Smaller than stage 1 because Stage 1 was all of your figs, and this is just a bunch of figs that look like they belong to the same army.
E.g. My Fynlund Imperians
Stage 3: Expanded version of stage 2. Just a bit more than the same amount of figs, but with alot
of cool vehicles now.
E.g. Robotmonkey's RIN
Stage 4: More figs, same amount of vehicles(Although some were modified or replaced to look cooler) and most importantly more character.
E.g. Freddie's AN
Stage 5: Complete. As much figs as you'll ever want in a brikwars game. Your vehicles are beautiful, functional and a good fit for the force. You've perfected your army by having variety but not looking chaotic.
E.g. Natalya's ASE, Roc's 45th Union
Stage 6: All your figs look the same. If everyone was like you brikwars would be the most boring and badly paced game on the planet. They're good figs, but it's made bland by the lack of variety and the fact that they not only fit in the colour scheme, but blend in to the colour scheme like camouflage.
Example: Any army by asterios
Amirite? Every army is a variation of these 6 stages.
