I doubt he was paying attention to grog's land at the time. All grog would have to do is explore as he's being attack and he wouldn't know the difference. You can land kill a target that's not online. But ideal land is below 2000 acres. The minute grogy comes online to explore you've lossed. He explores for 5X what you hit for every 2 turns.
We have spoken in the game several times, though he likely doesn't know me, but I believe this is the first time in the few years I have been back that I seen Gogy on this forum. I do not come here often, so probably just missing him, but good to see you Gogy.
