While waiting, I've had some success with a few baiting tactics. My favorite is...

We keep playing cat and mouse with me purging them (a la Ellay) or flinging out a lone spell volley or two. I can tell they're waiting for a good moment and talking it over via ventrilo. So I'll lay down a totem farm, then take one of my alts and sorta run him 2-3 yards ahead of the group and off to one side. (I'll switch to his client, and just run him a bit say 30 degrees to the right.) This breaks his /follow, and then I'll re-control my main and start jumping up and down and trying to move over there to "pick him up" again.

I fake a technical difficulty where I have a rogue alt, basically.

This will sometimes encourage them to attack "hey, he's got a problem, let's go now". As they start moving in, I mash my follow macro and Mr. Troubled Alt snaps back into line and it's time to kill them. I think I've done this 4-5 times now and it's worked all but once. It certainly isn't going to work more than once against most teams, but it's worth trying to be sneaky a bit and try to get them to fight on your terms and in your totem farm.

Use your partner for bait a bit too. I destroy any warrior who charges my Pally partner first. Love it when that happens.
