@Milkman your right as I am seeing lots of KDs just attacking and being aggressive with whatever they have.
I think if you consider the fact that most are Undead or Avian due to their overall cheap training vs other races...there isnt much unique variation in the population. Remember as well they reverted to the smaller unit values of the past as well besides all the new things to the game.
BTW im not against the changes tbh...but im sure next age there will be minor TWEAKS in order to keep the new change in the meta of the game but also allow the other attacking races with more expensive units to flourish.
One thing I just suggested is a 96hr EoWCF instead of 72hrs, Prosperous isn't the defensive haven as Fortified was...and if you consider the sudden negative reaction over increase of speed in the game it would be a welcomed change.
