Cav are more effective for there points and keep with the feel of the list. Also, with T5 and 3++ you're lords almost immune to insta-gib anyway, if you want a saga make him more killy (ie. use SotWB). The WG need a pod, and then they'll just rape LRs/LRBTs etc. You can screen your lords with Rhinos, they don't need 5 wolves each, just get them a pair themselves and use the points to get las/plas on your RBs. There you go.
