Ok so we should balance the game around crayon-eaters then and see what happens in the top ranks?
It's called trickle down balancing. They did balance Warrior initially for the bottom skill tiers by completely messing up Bloodwhetting so bad that playing it was actually detrimental. They reverted it after they stopped listening to knee-jerk reactions.
Skilled players know how to break your game if you give them the tools and likely have a better idea about problems in job kits.
Also I am not sure what arguments past this point I use average players as the basis, but feel free to point it out.
