I played generals mostly idol based earlier and I have to say they are quite bad now with 2 instead of 4 minions per idol.
But I asked myself: Why are they so crappy? And I came to the conclusion they are way to expensive.
So nothing new here 
And than I tried to examined the stats and noticed a 400 hp increase for minotaurs, 300 for archers and 200 for priests per idollevel.
So what are the other stats? Is there any datasheet?
Especially is the attack speed increased?
