"Zoning into an instance on a PvE realm will now drop your PvP flag."It's possible that I didn't read it because it's listed under the PvP section. But still... No more, getting on a bird before we summon you. No more having to have the entire raid flag PvP because somebody forgot to unflag. I'm not sure I've ever had a PvP flag and set off Raid Herpes, but it's nice to know that it's no longer an issue.
But it does raise a concern. I can easily see the exploit here. There's generally a ton of people parked just outside of any major instance. Karazhan is the first one that comes to mind. With just one person flagged, it usually causes some form of chaos. Now, you can flag, start to fight, and then if you're low on health, just run in to Karazhan and come right back out... unflagged. Just seems, well... kind of cheap.
I think I would have rather have seen the implementation that you don't get flagged PvP while buffing/healing a party member that is flagged PvP while in an instance. But then that sounds like a heck of a lot more code that Blizzard would have had to have write. And being that I'd much rather that they work on other things... it makes a nice change... for now.
p.s. Oh, and "Summon Warhorse is now available at level 30." Yep... you can guess the first thing I'm doing tonight.
