EDIT: WHAT about the "new" built in voice feature (wasn't around when I quit previously) - will I have a problem with that with WoW on the EHD??? Hi, I'm thinking about only installing WoW on my Western Digital Passport and playing through my USB 2.0 on the my MacBook Pro. I'm wondering if I will have performance issues. Will I be able to PvP as well as if it were on the native HD? I used to play WoW addictively, but now I'm trying to restart and just play on the weekends for fun in a limited amount of time. Thoughts on performance on EHD??
