I have to say, I'm not terribly impressed by this Battlegrounds announcement. Then again, I'm firmly ensconced in the PvE camp.

If I want PvP, I'll duel somebody or take the fight into one of the arenas that already exist in-game.
I also see this as a bit too "end-game" for my tastes. For all the work they've been doing to make lower-level zones more engaging, including the introduction of the auto-mentor (chonomagic) system, it doesn't seem sensible to make people feel as though they need to rush to level 80 before they can actually enjoy any major aspect of the game.
But again, that's just me.

Not being a fan of pvp, I pretty much agreed with this

That said, this past Sunday morning after a failed attempt at getting a group together for the SF mark mission of the day, the tank I was with suggested we try BGs, so on a whim I did.
Turned out to be surprisingly entertaining. Now, this isn't something I plan on doing long term, mostly I just want to get enough tokens to buy a sword from the vendor, but the BG's are an interesting diversion, even if my dirge ends up dying a lot

(If I get grouped with a decent tank, and by decent I mean one that can keep 'aggro' and take a beating, Blais does ok. Otherwise I end up chain mezzed/stunned, whereupon a scout will dice me up into itty bitty pieces, or I'll get blown up by a caster in short order, which for some reason I find amusing.)
For the most part they are pretty quick, and maybe I've been lucky but so far there's been very little of the chest thumping/trash talking that usually turns me off to pvp. I still think the gear you can get from doing this is too good - it's raid quality gear really -- (jewelry and weapons) but I don't see that changing.
