Jive: It shouldn't interfere with existing schemes, so don't worry - just don't be surprised if certain units lack hard-coolured eagles.
And...a shot of a current WIP...
A redone Skull Champion for Berserker squads
This bad-ass starts off with a Bolt Pistol and a Chainsword like most Aspiring Champions, except he's substantially better at CC. The Bolt Pistol is exchanged for a Plasma Pistol through research. The Chainsword is exchanged for a Power Axe and the Power Axe can then be exchanged for a Chainfist as seen above.
Yes he can gain the ability to lob Melta Bombs.
And yes he'll be in the update
