Let's Talk MoP Beta

[Shamago]

Sabra, I'm assuming standard WoW doesn't run like this for you, so there has to be some setting in the MoP client that's borking things up for you. Have you browsed through the MoP Tech Support forum at Blizzard to see who else has similar problems? Blizzard would obviously be very eager to hear about your issues; that's one of the purposes of these beta invites, after all. If you're having this hard a time, that means someone else has to be too.

I'm guessing that the beta client doesn't pull over your preferences from live. Going through the settings to try to match them up to the live client might help.
Also, try the "optimize network" option in the networking panel... I think it defaults on, and if you want it off, it's usually a bad thing when it's on.
