That's one of its main weaknesses, yes. There are some buffs, but mostly in the form of imparting new abilities (e.g. fly) than improving existing ones. The other main primal weakness is that they have very few spells requiring Will saves, which is bad because it is really useful to be able to figure out what an opponent's weak save is and target that. My understanding is that the relationship between player save DCs and monster saves more or less assumes that you'll be able to target a weak save most of the time.
In terms of offensive spells, yeah. I'll have to look over Primal again and get back to you; it didn't seem that bad to me, but I've admittedly not read them in detail.
