haha, I like the enchating your slaves with run speed and not your main. I think in the end this might be worse though, or such a minimal help that it won't be worth it. 2 things:

1. the tiny speed increase you get still won't make them run right ontop of you, so you still have to run in, stop, and wait for a sec on your main. It might be .2 less of a second of wait, but meh.

2. Idk if you've ever followed someone when you move faster than them, but you end up running, stopping, then running again. Thus your slaves might be in the middle of their stopping and waiting for you to move forward more, before you stop, thus making it take even longer.
(sorry, really hard to explain text.)
