The champion is strong and should remain that way, especially the cavalry. The real problem is how fast you can train this cavalry once you get p3. I mean, you don't see complaints from Han players abusing cavalry. If I'm in Athens, I'll hardly be able to create champion soldiers as fast as Gauls, because I need to build gyms. The real problem is in trainable champions in the barracks and stables, we need to put them in appropriate places, for that, we need new contraction models I think.
