Vastness in combat?

[von_Schmidt]

So I got myself a Vastness; the unit with the coolest description and graphic in the game (IMHO).

Throw in combat after GOR; and the V decides to use his (un-)amazing level 3 Astral spells instead of his much more effective sounding natural weapons. Both when set to orders NONE and CAST SPELLS.

So I decide to set it to FIRE WEAPONS - no go.
Attack rearmost - no go.

My question: how can I get the Vastness to use his 4x, 100 range, 100 accuracy, deadly sounding (not seen it yet tho!) personal weapons (forgot the description of those...)?

Right now it is acting like a 180g wimpy mage instead of a 100 gem Ultimate Street Fighting, *ss Kicking, B*ll-breaking Summons.
