The fear in SL does suck, but only a few mobs do it, and you can always pick your ground so that the inevitable fear doesn't mean a wipe. SL is one of my favorite BC instances, with interesting boss fights (time for FUN!) and a couple rooms that insist on delicate pulling. You should definitely do it once. I've got my new DK/shaman team up to 68-ish and would love to hit SL, 'cept I still haven't beaten Ikiss for the key.

For the Sethekk charms, try adding /tar Charming Totem to the end of your assist macro. It will sit there quietly until a totem appears, at which point you'll blast it and the macro will continue working as usual. If you don't want to do it that way, just keep an eye out for it and kill it ASAP. Time-lost controllers are the ones who drop it.
