A more graduale change might be, but I go for simplicity myself. That's what I love about Mordheim - the ease at which one can remember the rules.
(A little off topic, but...) God, back in my Confrontation 3.5 days, I remember playing a game of 4 minis vs. 3 minis and the bloody game took 45 minutes to play out. Sure, it's far more detailed skills/abilities/rules then Mordheim - but 45 minutes!
Anyway . . . I do like MLP's system too.
