I had played a Gilden game over the weekend, and wanted to post a couple notes on the Gilden special ability to create those constructs.

Overall I did not find the price to build one to be prohibitive. In fact, it was pretty reasonable for what you got. The problem I had with them was they had no offensive capability. Because there is only one construct in a unit, there is only one attack instead of several so it doesn't do much damage, and that one attack frequently misses.

Their defensive ability is quite serviceable, but it means the only use I had for them was to intercept melee units (ranged units were to smart to bother with them when there were better targets), and if frogboy's still working on tactical battle AI, the AI would do better to walk right past these units, until there were no juicier and more dangerous targets.

To make them more useful, I think their offensive ability needs to be improved. Personally, I think the fact that they have a hard time hitting is good flavor for a  construct, but make them hit hard when they hit. Give them a decent % boost to attack power.

I have no problem with making them more expensive as a result, but another possible way to balance their improved attack power is to give them a special penalty that allows them to only kill one figure in a unit per attack. The justification could be that they are effective against monsters, but groups of beasts (wolves, spiderlings) and trained units will use their numbers to surround and confuse the construct. Just throwing that idea out there.
