Well, I think the problem here is everyone has a different idea on what strategies and tactics as a whole we are talking about. Seems some people are coming from one angle while some are thinking of something very different. Kind of a broad spectrum of assumptions based on stuff we don't really know as of yet.
I wouldn't be totally against something like a waypoints like DF had, or some other form of signaling by certain spells. But I am alligning myself on kind of what Kaiser was saying though.
Information denial is key, dressing people in a certain way (assuming that its possible in this game) is also key, friendly fire, ect. Having a siege that lasts for days as opposed to a few hours is freaking fun. Artificial tools demean all of that.
For example, I'm against things like from PS2. Instant respawn points, maps that straight up tell you where your forces are in real time, and GUIs that show you green and red dots running around. It has its place in a game like PS2, but I don't see how it lends itself to a game that is not set in a sci-fi world, that as far as I can tell, is not CF. The most I would say that it needed to go was how summoning was done in SB, or runes in DF.
Hell, anything that deviates heavily beyond SB's style (minus and bug issues) has no place in a game like CF in my opinion.
