It would make Tyr one powerful god indeed. Hey... I need those tiles back. Skadi!!!! Need you to die for the cause again!!
Just a thought, but could it be set up so that first use of killing a god in a game restores 'half' of all the ruined tiles on the map (instead of all of them), but the second and third and so forth uses drop to miniscule amounts being restored, like a tenth of what is left, then a twentieth of that, and perhaps then a hundredth of that?
So using the 'kill a god get ruined tiles back' once is useful (but i strongly think it should be limited to some part and not all of the ruined tiles, but hey that is just my opinion),
but trying to abuse it, makes it still cost the 3 AP but only gives back a fraction of the first use. If players know this up front, and they should if we tell it to them in a tool tip, then losing AP points for fractionally smaller and smaller removal of ruins is way too high a price to pay.
Anyway, just a thought to stop the you know... over use of it.
