It isn't something that has been brought up much due to the massive amount of issues this game has, but I find the current state of tech and skills impacting my enjoyment much more than I thought it would. It is a disappointment I didn't expect at all going in, and for most factions things are in a BAD state.
I can understand wanting to tone down the buff stacking available to players, but this is just an under designed mess. You can randomly click on techs and it will have no impact on your gameplay at all for factions like Kislev and Cathay, while Slaanesh has only a couple good techs.
Just another aspect leading me to believe this game should have been delayed again.
