Been practicing with Kassadin on Dominion with smartcasting

I've been playing a lot of Dominion lately with a specific goal of getting better with Kassadin. I love the champ. He's super mobile, has really high burst but also a fair amount of tankiness (especially against a team with a lot of AP). His silence is one of the longest in the game and you just can't escape from him once he decides to kill you.

So Dominion is a great game mode for practicing all this as well as the new realm of smart casting (which is fan-frickin-tastic!!). I've gotten to the point where I'm always top three in a Dominion game and very often 1st place in BOTH kills and tower caps (which is an awesome feeling).

I realize that a big part of this is that I'm playing one of the wildly OP Dominion champs (Kassadin) but it's fun nonetheless. If you decide to play Dominion and want to win, I'd suggest any of the following:

Kassadin: Widely regarded as one of the three most OP champs in dominion. I love him.
Teemo: Shrooms will get hit far more often in Dominion. Build massive AP and watch people melt.
Heimerdinger: Can handle bottom solo against 2 or even 3 people once he gets Zhonya's. Played right, the bottom becomes an untakeable target.
Gangplank: The ult will prevent a cap of a tower for the length of time it takes (7 seconds). Very nice.
Malphite: So tanky. You can't play him in draft summoner's rift now. But you can play him in Dominion. Awesome.
Kha'Zix: High burst and a leap makes him mobile and dangerous as a wanderer in the middle. Lots of fun.
Evelynn: Wandering the jungle stealthed is fun. 'Nuff said.
Amumu: Tanky with a scary ganking ability. He works great for generating quick 2v1 kills on bottom and then wandering back to hold top forever.
Blitzcrank: Pulling from out of a tower to create a 4v1 that can leverage to a 4v3 is fantastic... Make sure your team is ready to instagib the poor helpless target.
Skarner: The ability to ult and pull people out of tower or ult and pull people into YOUR tower is fantastic. He gets tanky and burst all at once. A lot of fun.

Dominion isn't "League of Legends" the way it's supposed to be played. But it's a different game and for developing your skill set with a new champion, it can be really useful. Just remember, you can't cast that much in a regular game!
