Orks, right. Their problems largely stem from the fact that they can fill their FoC for a stupidly low number of points, and even when they don't try, they still find it far too easy to fill.
Those of you familiar with Sid Meier's Civilization games will know of the Infinite City Sprawl, and I'm sure plenty of other strategy games feature the same idea...
So, my idea, is the Infinite Shitty Sprawl.
For every 2 Troops choices the Ork player takes, he can choose a single non-Troop above his allowance (ie, elite, FA, HS NOT HQ) and for every non-Troop he takes (including these bonus ones) he may take an additional Troops choice.
