If your new i recommend getting used to the tactics side of the game with a bigger team, then when your more comfortable with the game got to LLM, theres loads of decent tactics on here to try so give them ago before trying to make your own.
As people has said already match preparation is important so you want to have different formations prepared and up to fluid before you go chopping and changing - otherwise its sure to take a turn for the worst. Don't undestimate teams talks either they play a huge part too and theres guides on here too.
