@Thyrfing: I have a couple of issues here, I'll break it down by line. By and large, I think this may be semantics, but worth picking out.

Against reveals, sure, agreed. Against planning too? I think we'll disagree here. You give some reasons that it might be bad:

There is a blocker or busdriver, although they would need to target someone who has targeted the chosen player, it's not that difficult
You say this like it's a simple thing, but I'm not so sure that it is. First, there has to be a busdriver in the game. Possible, sure, but by no means guaranteed. In fact, just by the logistics of such a thing, I'd argue it's not even likely. Second, said busdriver has to be scum. Again, possible but not guaranteed. Third, for a scum busdriver to mess up the plan, they'd what, target the person we've publicly decided will target the 2nd highest vote getter? That would mean the town still knows about the existence of the vigilante, because a kill still happens (presumably), and we now know about the existence of a scum busdriver. Net info gain for the town. Even if there is a scum busdriver, I don't see them interfering so obviously, even if the vig kill ends up hitting scum - that's a lot of town cred to be able to claim.

What do we know with this plan? Either the end-player lives and we know that a) there's both doc and vic b) there's no vig but we don't know about the doc.... I think the combinations can be too much to extract any information of value.
So I agree with you that we shouldn't have both the doc and the vig target the same person. I'd much rather learn about the existence of the vig for sure. That said, do you not see the value to the town to be able to direct the vig kill, if such a thing exists? You list two combinations, but think that's too many to get any valuable information? I'm not sure I'm understanding you properly. What information do you think the plan COULD gain the town? What possible negatives do you think outweigh that information?

The player we choose to target is scum in the first place
And this is a problem because...?

The doctor/vig are scum
Again. Problem because...?
Thyrfing wrote: 
It gives scum more options for cover in the future (eg saying they are a town vig that targeted that player to cover up for a night kill)
No, that's the opposite of true. If we have the vig under town control, the scum cannot claim it as a cover for a night kill. Elaborate on this please.
Thyrfing wrote:Also as Telleo says we will know what ability we have used, so we will know if there is a vig (provided a townie gets it). Revealing that only seems like a good place to start getting some information and at least we will know some of the roles that are in play. But definitely I would leave roles to act on their own and not try to control them, at least for now.
Millers should reveal of course. Other town roles that might not be "100% town" I'd say to stay quiet for now.
This just doesn't sit right with me. You say revealing gets us information, but you don't evaluate why that information is good or bad for the town. Give me some analysis - why is it good to let everyone act freely, and offer no control whatsoever?
You've got a handful of thoughts that don't seem flushed out here. Fill them out for me please.
