Comment 12 for bug 744749

In my opinion, the training sites should be handled similar to production sites and therefore show their productivity (rounded to 5% like all other buildings do).
The current information ("Training attack from level 2 to 3" etc.) is not very helpful to me. When I am interested in what my training site does, the information displayed in the tooltip (when hovering with the mouse pointer over the building, e.g. "Failed ... because bread is missing") is more helpful. Or I simply open the building window to see what wares are inside and what levels my soldiers have.
The information how many soldiers are inside the training site is not very helpful either (I agree with comment #1). Furthermore, training sites are very different from military buildings: They cannot be attacked neither can attack themselves, but need regular ware supply. They therefore resemble ordinary production buildings.
