Yeah, after watching my Dragonite and its teammates get demolished by jas' Volcarona twice today, I'm definitely impressed. I think it's the only Volcarona I've seen in this playtest, and it definitely seems to be worth trying.
I've been running QD/Bug Buzz/Thunder/Hydro Pump on my Aurumoth for a while now, but I sometimes find myself wishing I had some other attack. I don't think I could use a two-attack Aurumoth; the 4MS would get too frustrating. Those of you that do run it: do you find that this is a problem?
My record has gone off a cliff lately, but one set that still does fairly well for me is DDTar with Fire Punch. Earthquake really isn't missed in this meta, and Fire Punch tears through tons of Genesect and Ferrothorn, which tend to just stay in. In fact, I've come across a few teams that have no real answer to DDTar other than Ferrothorn, although those may have only been at the lower end of the ladder. Of course, there's also the original reason I started using Tyranitar: to remove rain.
Speaking of Genesect, I'm generally fairly conservative about calling a Pokemon broken, but I think this one qualifies. I guess that's the least relevant part of this post, but it was a new discovery to me since I had never played BW2 before this playtest.
