I found a CM exploit, however i dont know if you have it alrdy as i cannot see the other stuff. Anyway....
Theres a ledge, that allows you to pull every Lode in CM, and kill them via PBAE or CAE. It is right next to the passage towards Weeweres.
Also i have a way to Focus Pull with as many people in the group you want, without getting aggro on your grp members. I call it the Invite Pull. Basically, you macro everyone in your group with /invite and /disband. when you pull only have 1 other person with you in grp, everyone else out of grp. Then pull. Once all mobs are back to a safe non-aggro area, invite everyone else and proceed killing. Ive done this at Fins, at Siabra Island in the Bog, and many other high aggro areas.
