Do you use honor summon when event to boost up your units and Zel or Use when non-event, to get a higher chance of getting starter units & evo material units. Alltho no one confirmed or test how the higher metal/jewel units probalility raised. Is it when we get crap units then the metal/jewel unit is up, or Is it added big chance from the first time (thus reducing the chance of starters and evos.)
