That and I find pretty BS that Dolls don't gain negative values from passives. That's just weak coding.
If I'd do anything to buff Sadida, it'd be to give them some WP spell that enhances their healing. Maybe on Harmless toxin for some effect or the next. Maybe Mudoll to increase heals from dolls. Maybe just buff Voodoll to enhance heals in some sorta way.
There are just people who play this class that are comically resistant to change. I think a lot of people are very defensive of Sadida because the people who stuck through the class when it was at it's worst have an ingrained paranoia about going back to the days when it was nearly unplayable, and easily the least welcome class on any team.
This paranoia and/or desire to exploit the exploitable seems to cloud the minds of a few poignant individuals.
That's my theory anyway.
