AS I just wrote in the patch thread from yesterday, multipliers now work correctly.
I've set the recruit cost to 2.5x in a game I started today and it helped quite a bit with the problems I had with the RTS combat.
The effect is that battles now develop slower, have less additional units and initial units are very important.
I even manage to win fights with no or relatively low losses, if I take some care.
Consequently the high loss rates in autoresolve could be toned down as well, without having to worry too much about balance vs RTS.
Now, I understand that it al comes down to personal taste, but I feel that the game is (even

) more enjoyable like that. The only downside so far is that difficulty might be too low, since the AI (medium) fields too few units on the strategy map.
