I was playing Lord Erebus and I noticed the tooltips for the Morale Skill line are identical. They read Morale I, II, III, IV, etc... but the stats are the same. I havent' checked with the other generals, but it's definitely the case for Erebus.
I hope this is just a bug for the tooltips? Can anybody confirm whether or not the effective of Morale actually improves with more points in it?
