I am not arguing against using a GK as SC, but I just feel that I have time using him in battle, so I dont want to waste my design points in Air & Water.
Sure, my GK is site-searching to get me those earth gems (since Bloodslaves for bloodstones are only available until I get enough blood-sages and I only forge a few clams (4-8) to help with immediate gem shortage and to enable my astral-sages to cast probing). But since my mammoth occupy a province a turn and since my scouts usually find some easy targets for some windguided archers, my GK is heavily overstrained with site searching and as soon as I got enough earth gems for a hammer, he will barely be able to leave the lab. So I rather ensure good scales and never waste much thought in using him anywhere on the front. He might be of some use in defense, but I did that once (in hostile dominion - yes I had overextended) and immediately gathered two affilictions, which encourages me to stick im in a lab...
