To be honest, after my first couple months on WIS, I haven't spent much time at D3. I just recently decided to try to keep a team at all 3 levels, so I've been researching how best to approach D3 recruiting. As for battling, I'm MUCH more likely to "go to war" for a recruit at D2 than at D3. One of the reasons is probably that when I first started playing, I tried to battle a couple of times, and got burnt pretty badly.
