Proppes use of arrows and tactics?

[Tactician]

For example,in a defensive strategy,I'll use only red arrows for offensive players aml,amr and st,
no blue arrows at all for defense,and no arrow for other players.

In an offensive strategy,on the opposite,only blue arrow for 2 dc,and no red arrow for offensive players.
No arrows for the rest of the team.

You might be right on some points. I need to test that.
