You mean like, an npc that just moves side to side? Yea, t3home2 and the valley of the jedi have different variations on something like that.
Although I don't personally like a lot of the things on t3home2, but it has some good training equipment. The Kyle's with hp counts was probably the most useful thing on the entire map in my opinion. So as far as a list goes...
-Kyles for damage explanations. This pretty much covers wiggle/poke lessons, but also
-Thin poles for aim practice. I like to use the poles in the CY of ffa3 for teaching it early because it requires more accuracy to keep it in a pole that thin than it does to hit an npc.
-Strafe training areas. No, not those lame strafe pads either. 😛 I usually teach strafe basics in the CY on ffa3, I can show you what I mean later but I think there ought to be an area for teaching that because its kinda core to the game, and to combat.
I'll post more as they come to mind but those are probably the most important actual training items, aside from maybe something like what Apoc had on shola with the revolving spinning things of doom for timing practice. A lot of the stuff that really matters needs to happen in sparring practice.
