Well ive been playing RTW and EB for years now but when I look around on the forum I still read stuff that make me say "wtf I didnt knew that"
For example: I just read that you putting your hoplites in guard mode on the walls is not good. I had no idea (I usuall fight with guard mode on). Why is this?

Are their any other things that most ppl dont know but that can save lives/give an advantage/.... ?
