I just played my first game as the Thalans.
I'm a big Altarian Resistance fan and a diehard turtler for the most part. And while I got my butt kicked by the Drengin, the Thalans, with their unique tech tree, are so close to being great fun. I really like the concept.
I'm not sure what would make them just right, but my first thought would be to give their level 3 buildings 2 or 3 more mp or rp, along with the reduction in maintenance cost. Even if it takes longer to reach level 3, this would make a big difference.
This wouldn't help them much on suicidal, smaller map games, but they're a sitting duck as they currently are.
As an aside, you guys/gals are very cool.
