Sorry I don't run Exalted and I've only played one horrible session (like I haven't ever had a worse experience) but I can relate to you problem. I had some D&Ders playing Vampire and of course the tankish guy took all physical and uber combat powers. He tried to pump a fledgling Ventrue for information but the Ventrue Dominated him, after that he started spreding out the XP over all the abilities. So my advice is poor through the book for some low end powers that will easliy tip the balance.
