+1, I hate custom lore.
BUT, something that might could work is, instead of removing it, changing the whole thing, making a cap of 10 sith (1 lord and 9 apprentices but these number could change if anyone as better then this) and wipe the current sith order other then their High command (Current dark lord and his dark council member)
I hate custom lore, but sith RP is something that can always be entertaining if done right but right now it's just a bunch of people who goes on it just to pretty much mass RDM, the RP is really rare and most of the time you engage them they run away in lake to either heal, or wait for you to leave them alone.. it's just boring and repetetive, when I see a sith coming up to me as a civilian or even as sith I, most of the time, just ignore them because interacting with them isnt fun, "just a walking stick btw"
