I think kun-whu fix was needed but badly-handled both by players (one said it was perfectly doable with 2 rogues but never talk about charm ofc) and devs.
Both adds & Death of Qian nerf were un-needed but sure, they have to do something about the heal vs charm.
Rest of nerfs/fixs were okay and contribute to make rotg a more balanced expansion. Only sad thing is most of fixs comes lately and some issues (factions stuff too grindy, some dungeons unplayable...) have decreased the popularity of the game too quickly.
