Since I've been having very good results with it, I though I might as well share my Water/Aggro Rogue list with you. At first I though that the deck didn't surive the rotation but it seems to be very powerful still. I threw this list together at rank 260 or so when I dropped straight from rank 45 since everyone was hating on Quest Rogue so much. (The Murloc Paladin / Pirate Warrior Matchup is pretty tough with Quest..) and after grinding a little bit, made it all the way back to top 50.
One of the main reasons to play the deck is probably still Finja. That card is just sooo busted and completely warps the game when one player has access to it. Pair Finja with the aggressive / tempo heavy playstyle that Rogue offers and you're good to go. Many decks actually have a tough time beating a 5/1 Divine Shield for example.
The Playstyle can sometimes be simillar to a very linear aggro deck like Pirates but there's a lot more options / lategame in our deck which I enjoy a lot. Also most of the aggressive matchups are very favorable due to our fast clock paired with efficient removal.
I might do a guide on the deck once I've picked up a little more experience with the list but I feel that this deck has the potential to become a Tier 1 deck so I hope that you enjoyed the small write-up :)

Edit: replaced Argent Squire with Fire Fly. Not sure if that's right or wrong and I love the Cold Blood + Squire combo, but Fire Fly is a pretty sticky minion and the 2nd toughness is oftentimes as good as divine shield. Sitting at rank 19 at the moment and liking the deck's position in the meta a lot still :)
Edit: new season high at rank 7 on EU Ladder at the moment. :) http://www.bilder-upload.eu/show.php?file=7d3e59-1493374282.png
