While it is true that leadership is the primary skill of TLs, weapon skill is required not only for self defence, but to gain the confidence and respect of their troops.
At the risk of diluting the above point, some possible solutions:
* small chance of gaining appropriate skill during a training session, which is gold and time inefficient compared to academy.
* tweak battle skill gains. I think a character who fights a reasonable battle every week should have the appropriate skill around 50%, not ~20 as it is now.
