Well for one, i've od'd dd setup shades even in my pvm setup, and yes i've od'd shen/piercing shades too. Happens quite frequently really. I've od'd crats even since last patch, engis too. Only crats that tend to od me is full on dd crats. But i do hear your point, by majorly od'd i ment that it doesn't happen really all that often at all =)
About overagroing if you meen that you want to be able to do tons of dmg without getting agg that seems well a bit weird, with more dmg comes more aggro simple as that. I wouldn't mind if shades got more dmg on their perks (seeing as drastic perk changes are incomming so why not fix shade perks for more dd?)
And i never ever hold back, a proper doc should be able to keep a full team healed without problems since doc heals are the nerfiest =P (everything's just a cakewalk nowadays....)
