I wish GW had gone all in on the upgrades to the archon theme. If the court worked like a deathwatch kill team, conferring bonuses onto the entire court, it'd be awesome. So how jetpacks, bikes etc all give a different benefit, the court could do the same. Ur-Ghul 3d6 charge pick the 2 highest, lhameans reroll 1s to wound etc. So you can build a court to actually boost and tailor your Archons role.
