I ain't never been to AV (been to the other three battlegrounds now, but this'll be me first trip to the Valley). Not sure what to expect, but here's what I does know:
Number the One. Is supposed to be a good place to get honor points
Number the Two. There's a lot of PvE as well as PvP
Number the Three. I need 20 AV Marks of Honor to buy the S1 gauntlets, which I wants.
Number the Four. Is more complicated than other battlegrounds. Wowwiki sez read everything we tell you about the place, and then you still won't know jack about it.
Number the Five. Me GM Tarsius said it were his favorite his favorite battleground. Then he retired to Mulgore to grow herbs. No, not them kinda herbs. Well, maybe some.
Number the Six. Sometimes in battlegrounds you's the hammer, sometimes you's the nail, and sometimes ya just cain't tell. Best not to worry about it and just haves some fun with it. Ain't like these is really battles, not like in the old days. Now is more about givin' the goblins somethin' to bet on.
So that's what I knows about AV. Maybes I see you there, then we go have a pint at the World's End Tavern afters.
