And where does that trial and error come from? Theory crafting on target dummies for hours while running a parse to gauge the difference in damage. Every single rotation video on Youtube is someone who spent time with ACT running and compared their damage with other players. Take parsers away and you're literally throwing darts at a board and hoping something sticks.
