Ah, so I'm not up to date and those issues I mention about attack and defence values were already solved.
Yes, that happens if you don't want to play
As for the part about trainers, the atlantean issue could be fixed by having the master trainer be a different worker that has to be made from top level military gear. so atlanteans would still need to make 2 sets of high level gear before they could promote any soldier to full.
Maybe it would be better to make those changes optional, because the current game is really good.
I still do believe it's best for the game balance if we stop the ways to get early supersoldiers. the game is made with many different shades of soldiers, and it is a shame to skip through all of them. Plus, it would be much easier to get balanced tribes if we didn't have to worry about the advantage of having the supersoldier 10 minutes before the opponent.
There could be new difficulties about balance. And imagine all the annoying micromanagement if you have to send the same soldiers into the trainingssites over and over again.
