Seems reasonable to me too. Inspiring words is better then healing words, but you can only use it once per encoutner so that seems fair. The at will powers seem a little weaker then those of the cleric, because they can't be used at range and target AC, but the encounter power seems better then the cleric's so it kind of balances out.
Most likely the warlord has some other bonus too which we don't know about, kind of like how the cleric has his turn ability and his other ability that can be used in place of turn. But kind of hard to model that.
