I am a brand new player coming from AOE 2. I think i started in early January and mostly play seton's clutch land position. Before I complain I want you guys to know that the game is really fun and I am kinda addicted. Watching other people's replays is really accessible and I have been learning a lot by watching 1k+ Setons games.
Imo, there are no accessible build orders. There are some from Heaven on youtube but those are more general concepts and don't contain builds for every map. If the client had just some basic generic build orders for setons + other popular maps that work 80% of the time that would be great. Nothing fancy, just something to get people started.
AOE 2 takes it even further. There is a mod that walks you through step by step with voice direction each of about 11 different build orders. Then at the end, it gives you a grade of A-F based on how fast you could preform the build. There are builds for fast castle into knights, fast castle into Unique Unit, scouts, scouts into skirms, scouts into archers, archers, ect. If something like that existed for FAF then learning the game would be much faster.
Learning hotkeys and build orders are really the boring, initial investment into an RTS that a lot of people just fail to overcome. After you are over that hurdle and know several build orders and are comfortable with your hotkeys then it is smooth sailing.
