Do you still get the +2 strength each turn? I can't see any separate rules in the mini rulebook to say otherwise but I remember in previous additions it only added +1strength each turn because of trying to control the mount as well.
Well at the moment I am trying to write rules for lion riders for High Elves, so was seeing if the white lions would have the +2 strength, think they will need to cost a little more with the +2 strength rather than +1
