After a long weekend of playing a whole new team on my shiny new four box setup (upgraded from 3 on Friday night ), I have pretty much the same observations as you guys.

>follow only when the main guy is moving, unfollow as soon as he stops.

I have a "formation" button set up, which sends one of my characters to the left, one to the right, one backwards, and leaves the "master" standing in the middle (i.e. doesn't move him at all).

Obviously, that has the effect of breaking the /follow.

I didn't tend to use it very often, other than for visual effect, or when I wanted to park the team somewhere while I send the master in to collect the next batch of sharable quests.

Interestingly, I started using it alot on Sunday, getting into the habit of hitting it just before I open up on my next target, and I had ZERO disconnects on Sunday and Monday, after having had several on Saturday.

Fluke? Maybe. Something to try though.

I hope that helps in some way.

Most annoying, though, is that I've managed to get characters "stuck" in walk mode after coming off follow, and only a client restart fixes it. That happened twice over the weekend
