DNC and BRD both “support” in the sense they have large buffs that contribute to their rDPS but also have effects that increase their pDPS, they are still 75% carried by their pDPS. If this is your idea of support then you really aren’t changing anything except enforcing 2 selfish jobs and 2 “support jobs” as we currently know them (ie jobs that have non interactive raid buffs they just press because they exist). If you do it this way you need to rip raid buffs out of some jobs that have them because right now it’s 4/9 in favour of raid buffs
True support (ie near zero pDPS potentially zero rDPS as well built entirely around buffs, support and debuffs is an entirely different thing
