So, on travel (again!) and I'm in Chicago. Went to the Science and Technology museum to see the captured U-505. Got me thinking. The amount of technology and the benefit the allies gained from capturing this U-Boat was significant, and I was wondering if the same thing could happen in elemental. Instead of killing your opponents outright, you opt for capturing. A separate button in attack reduces your attack and defense by half or so. If you defeat the enemy, they are captured, instead of killed. I'm not talking about capturing swords and armor to use on my troops, but I'm instead thinking that if you capture an enemie's troops, you gain a permanent bump of attack and defense against that enemy in the future (it would be a permanent buff against that opponents technology). Not large at first, maybe 1%, but if you capture instead of kill for 10 combats, it starts to gain momentum. It could speed up the end game where you know you've beaten your oppenent, you just need him to realize it. Maybe if you have more than a 20% bonus against that opponent, he capitulates.
Anyway, more food for thought.
