Think carefully then, because:


 * If Penetration, you're pointing to only increase your damage output.
 * If Reduction, you're pointinng to increase the damage output of both you and your team.
 * If Flat, you will be dealing more damage to low armor targets.
 * If Percentual, you will be dealing more damage to high armor targets.
 * A combination between the aforementioned, if not managed well, may lead to eventually deal true damage if their armor reach 0.
