I don't think anyone will grab wisdom at level 6 if earth and logistics have already been given...
:confused:

Actually, on the 2nd-3rd week it's not level 6 :) We are talking about 12th or 18th.
There are often 3 booths at the respawn. And what's wrong with a 3rd tower in the swamp? The second one is definitely already there. You get own reinforcements after being defeated before the rush. And that's exactly level 3 for cavalry. Water is the most likely for bots, if there happens to be water :) What else would it be then? Well, and anti-magic in all schools. (Of course, I'm talking about TE this whole time, not the long-forgotten SoD)
