The Novice Support System is the menu that comes up at the start of a match, you can choose between beginner's mode and expert mode. If you choose beginner's mode, all your items and skills will be selected for you, however this can be un-reliable due to the fact that the game doesn't always have the best set and items pre-programmed to be picked.

Expert mode is simple, all items and skills are chosen manually, this requires good knowledge of the game and it's items.

Novice Support can be disabled in the options menu.
