even without element weakness LS effect, having element adding is the most surefire way to increase your dmg, by 1) 1.5x if you added strong element, 2) preventing reduction of 50% of your dmg from weak element. This works 100% unlike critical (70% cap) and spark (chance of missing hits, and not all hits can be sparked).
