I had some time this morning while people were getting ready.
That Untamed Hatchling posed some problems for me. I started with Tail Sweep, but amazingly his 260 speed was too fast to consistently get the second hit. I used Spiked Skin and Healing Flame, which occasionally allowed me to get the dragon buff and hit my opponent for +50%, heal, and get the dragon buff again because spiked skin caused damage that round, so that was neat.
I thought Plagued Blood might proc off of Spiked Skin and give him some more durability, but Spiked Skin doesn't get the heal
I rightly assumed I would run into a fair number of humanoids and didn't want the first slot on a Scourged Whelpling because I would have too many dragonkin attacks, so I went with a Restless Shadeling. I also wanted some sort of avoidance, so I put an Imperial Eagle Chick with Lift Off in there. I have never used any of these three pets in pvp, so I was excited to try them out.
Unfortunately, this team failed hard. I think running into Lil' Rags, Darkmoon Tonk, and Murkalot repeatedly didn't help. I put an Emperor Crab in for the Shadeling because he wasn't doing much against Murkalot and Plagued Blood didn't have the synergy I had hoped for, and the Crab owns Rags. Then I switched the Eagle Chick for a little more avoidance with a Flayer Youngling.
This team won a couple times by pitting the Hatchling against the Tonk, Crab vs Rags, and Flayer vs Murkalot. It was mostly carried by the Flayer, and the Hatchling was clearly the weak link, but he ended up being good enough to take down the Tonk, which is no small feat, imo.
Denarian, I used to use the Shimmering Wyrmling
a bit when Deflect was Reflect, but not since the change. Take him out for old time's sake.
