So, I've been wondering one thing and I finally thought that I would shed some light on it.
I really like what you done with the MoP rep, you hit revered and your alt(s) get double the rep for that given faction.
Now I love to faction grind, not only with my main but also with any alt I create, I thrive to get everyone of them to exalted! (insane but the way I like to play)
Now I wondered, how come you don't make the same change (revered=faster rep for alts) for the old factions. If you reach revered with your main first, it would make our and our alts lives easier, cause the second time the rep would be 2x!
I can even RP it, I just figured the faction knows my main (who is revered/exalted) and therefore I climb their ranks a bit faster - can't really see anything negative with it.
Thanks in advance!
P.S loving 5.3!
