I'm considering dropping the wildshape feats, because whoever said their friend didn't ever feel the need to head into melee, I can see why. The summons are so powerful that I would just pale by comparison. The only strategy at this point that would be worth a damn would be to have the fleshraker and I venomfired while I'm wildshaped into a fleshraker too. But I wouldn't want to put myself in danger while I can just sit back and let them do the work.
See, I told you. I was typically putting my friend against things that were CR 2+ above him. Eventually it came to the point where the only thing that could truly challenge without being ridiculous (Hi, I'm a Tarresque and you're level 10. Let's be friends!) was having him fight himself. Those creatures are immune and resistant to so much it's unbelievable.
As for summoning feats, what did you settle on for your build? Do you have the Greenbound + Ashbound + Augment Summon trinity? You might consider Summon Elemental from the Complete Mage. It lets you have a nifty Elemental that you can summon infinitely and it gives a +1 CL bonus whenever you're summoning. It might be a good idea to pair it up with that Rashimi Elemental Summoning or whatever it's called from Unapproachable East. It's more for utility though.
If you're not interested in Elemental fun, maybe Rapid Metamagic and its friends? Also if you got Spell Focus: Conjuration because of Augment Summon, Cloudy Conjuration could be useful. Not only could send something ridiculously powerful and broken at them, you can make them sickened too. Only problem is that you'll give your summon and it concealment. On the plus side, you could instead have the cloud pop up near you and give you concealment.
http://brilliantgameologists.com/boards/index.php?topic=3140.0 That'll be helpful. It has a large list of creatures that already have their greenbound template on them. The only thing you'll have to do is adjust them for augment summon. When my friend was playing as his Druid, he referenced that alot.
