So I've started playing AoM again after stopping when I was like 7-8yo. I've completed the campaign a couple of times and now I want to try going into competitive/vs not AI. I don't want to get stomped on every game. Any tips?

I like to play Set and some Hades and Zeus. Are armory upgrades worth? Is converting animals worth? How should I play for late game? Any key bindings I should learn? Also any keys on how to control large groups without having to reorganize after every mosh pit? Sorry for so many questions. Thanks
