not really, this is true only in case of relatively equal strengths, but if your enemy has a much higher strength, the withdrawal bonus is much more useful. In particular, attacking fortified units with good withdrawal units means wearing down their resistance, they will not gain xp if you retreat while you will and you will be able to take that combat promotion later and actually kill the unit with less losses.
Good point, so when your Warrior with 2 XP (Who has combat one) comes up against an opposing warrior with 2 XP (Combat one + Shock) then even though eh's got +40% on you, you'll have a chance of surviving!
Also, the whole 'wearing down' a unit generally only works if you have more than they do (Or with assassin's). We assume that we already have weaker units... why then would we assume we have the economy to outproduce them?
Even greater still, if we are adopting some sort of 'defensive' strat, we aren't even getting the withdraw rate while in a city.
