I've really enjoyed IFZ so far, really impressed with the content.
I've been dwelling on a thought about a training grounds, it would be too easy to just place troops inside to train skills or increase stats without some sort of "threat" applied.

while training troops, increase the draw of hostile invasions due to noise. possible injury to troops as a passive chance. something to make it difficult but rewarding also.

The training could offer;
unit speed increase %
Unit health increase
increased accuracy/damage.

These increases don't have to be big or too much of a give away, just an intensive to train troops

how to do go about offering up this suggestion to the Dev's for consideration?
