because defensive powers are rare and harder to come by and offensive powers are easy and plentiful. Of all the defensive powers only force sense power and dodge create despair. and dodge is pretty spread out over a lot of trees getting to an additional rank in dodge will usually take a lot of xp There are several combats where 1-2 despair at the right time ends the combat in the players favor. A lot of people crap on triumph and despair and say they are not powerful or its only 8 ish % but trust me in a narriative game it really matters and with the ability to trigger it multiple times per round it is very powerful.
