Pros outweigh the cons (not forgetting that the Duskblade would already be allowed to change out/alter spells to suit)? Terrain alteration spells dealing specifically with desert terrain are going to be undervalued weighted against a locale appropriate campaign. The character concept in question will be wide ranging and those spells are being at a disadvantage.
