Because of the higher power + precision. This build doesn't stack a lot of might, so going too much into hybrid / cele hurts your damage (especially against someone with good cleanse, then the conditions can't make up for it). Cele can give you more crit damage, but if you crit less and with a lower base power, it's not worth it imo.
Always cool to see how beginner pvp peeps forget to use the skill that usually does the most damage (auto attack chain). xD np mate, it was fun to watch!
