This weeks' patch doesn't bring much in the way of improvements to the platform, but we do get two fairly interesting new heroes: Disruptor and Undying.

For more about these heroes and their abilities, look no further than their entries on the Heropedia:

Both these heroes should see a decent amount of competitive play. Disruptor serves as one of the most powerful disablers in the game, while Undying brings a great deal of push and teamfight.
