how do you dual box 2 rogues?

I have keyclone, and I was wondering how you can dual box two rogues at the same time, or even a rogue and a druid in cat form at the same time. It doesn't seem to work right if you try and control both rogues simultaneously with keyclone because theres a delay in commands so the alt rogue always seems to veer off the path, and if you use the /follow commands it seems like the alt rogue will never be quite close enough to attack. Can someone tell me how to effectively do this with two rogues or rogue/druid (shifted)?

Lots of practice. This is why many people prefer to multibox with only one melee class. The best I've found to do is to add your movement keys (WSAD) to the do-not-pass list, keep the second rogue following the first and backup the first at the start of combat. This gets the second one into position for normal combat with one in front and the other in back.

Learn how to position things between your main and your follower. If you are just killing regular mobs you probably don't need to bother with stealth so just run through the mob and try to get it in-between your main and the follower. Note that auto-attacking will break follow.

Eventually use Shadowstep.
