I'm not too concerned if at this stage the AI doesn't use these types of powers properly - I'm more interested to see how they could implement it such that it could be used in multiplayer (I'm pretty sure I'll have sorted out the mp issues for the Mac version by the end of semester - otherwise I could dual-boot the Macs with Windows (that should definitely be supported at the school by July) and install there.
This idea is a good one and introduces some interesting RTS strategies. Anyone who played Emperor: Battle for Dune might recognise this kind of skill from House Ix - the ability to create a holographic version of any unit you own. It attacks like any other unit, but as soon as it gets touched (by another unit or by any kind of attack), the hologram dies. You could create 60 holograms, get in one barrage of fire (by then the enemy will have attacked and "wiped out" your "army", then attack with your real ones - nice, cheap and (if used correctly) effective. These was also a faction (House Tleilax) which could convert your units into units of its own - they became "diseased" and ultimately morphed into the Tleilax unit (which could then be used to turn more units, etc etc - kinda like Zombies I guess).
This kind of approach could also be used for things like undead units that eventually decay and vanish - a nice temporary army that could make a difference in a tight defensive situation.
