Yes, Daneck, my human mage, hit level 80 yesterday. And then I started the Wintersaber grind with him. Not sure why, just something to do. Inspired by seeing the Venomhide Ravasaur quest on the Public Test Realms(which looks insanely easy, even though it takes 20 days worth of dailies).
The Midsummer Fire Festival has helped quite a few of my alts level up. I've done nearly all of my 'under 60' characters, and just about all of them got at least one level. A few of my 'over 60' characters got quite a chunk of xp as well. Though I really don't do the "desecrating" of the other factions flames(except in one case, which I will discuss in a moment), so I really only get about 1/3 of the possible XP available. Fine with me.
I DID do a little bit of desecrating with my mage, Daneck, as he is working towards the 75 pet achievement, and the Spirit of Summer makes #61 for him. My druid and rogue had gotten this back way back when it was a quest to obtain him. They also got their Fire Festival Crown for stealing the opposing factions cities flames 2 years ago-before achievements. And even though I still have the crowns, I did not get credit for that achievement, and I am not interested in making that run again. So none of my characters will have the Flame Keeper/Warden title, and that is fine with me.
And then there's Ahune. A boss I never thought I'd see, but they left him at level 70ish this year. So my hubby's Paladin, kid's mage, and my druid have been 3 manning him. And after 14 kills we haven't even seen the pet drop yet. Sad panda. There was that one run where we wiped...because our power went out when we had him at 10%. I'm certain he would have dropped the pet that one time. Grrrr. So all cloaks and LOTS of them, 1 staff(my kid wanted it badly) and 1 enchant(for my druid) so far. And lots of those stupid cloaks. Grrrrr.
