Morale does nothing right now. Better food will boost morale though, with meat being the most beneficial, however if you don't feed your men, they will leave. Now, with tactics skill, i have a suggestion. With the last patch, the battle size was increased 50%, and i recall armagan stating he was going to increase it 50% more with the next patch. That means that battles will be 125% larger on max size as they were originally. So, wouldn't it make sense to at least double the effectiveness of the tactics skill to help compensate? Those 4 extra guys help out alot more in the original system, but with larger battles, it makes less of a difference.
