What are the Cleric's domains? Have him take fire and toss spells when needed.
I have a cleric of Sarenrae in a Jade Regent game and she's been tossing around Admonishing Rays and burning hands like they are going out of style. And working towards the preferred spell feat for Fireball when she gets her next level. Ironically shes the blaster as our Wizard focuses on buffs and control spells a little more. (not to bad in melee either, except she has terrible Hit points.)
Switch Hitter style Ranger would be good. Basically take the archery combat style and use your normal feats to grab a few melee feats and quick draw and you will be able to cover melee and range well.
He will still get more than enough fire spells to offset his cleric spells if they need more ranged combatants. But being a cleric he can also toss his divine spells out or get into melee. Nothing to do with filling out the classic MMO roles and more to do with giving them more combat options.
But if he really likes blasting, preferred spell feat fixes the domains lot only issue.
