Heroes of the Storm has a new update that has been pushed to the live servers, adding Overwatch's master of the beats Lucio, buffed new hero Valeera and totally reworked Murky. And there is a crossover promotion where playing World of Warcraft heroes can get you a new mount in WoW.

In all, 17 heroes were tweaked in the patch. Murky got the most significant change, adjusting many of his abilities and levels at which he gets them, while adding some and eliminating others. "In examining Murky, his original health and egg timers are vestiges of a different time, created before even Jaina entered the Nexus," the dev notes said. "We wanted to give him more base health to make him a little harder to burst down, but traded it for a little longer time to respawn from his Egg. This has the added bonus of allowing a bit more counter-play to hunting our fishy friend. We also wanted to adjust Pufferfish, as an increasingly high amount of the roster could immediately explode it. Finally, his talent tree has been updated to come in line with our new philosophies." 

New hero Valeera, who was added last month, also got a buff. "We feel that Valeera needs a small increase in power to help her overall win rate, but are hoping to do so without adding much more burst damage or disabling effects. The changes to her Health and Basic Attack damage should give her a boost, while the changes to Talents, Ambush, and Garrote should create harder decision making for the Rogue. While we were looking at her Health Regeneration, we noticed that it was actually higher than intended (most Heroes take 480 seconds to regenerate their entire Health pool), which is why we reduced it slightly. We’ve increased the duration on Cloak of Shadows so that predicting Abilities is easier to accomplish. We want it to be a rewarding, high skill-cap ability, but with the old tuning it struggled to compete with Smoke Bomb."

Finally, Blizzard is offering a cross-game promotion where players who complete 15 matches using World of Warcraft heroes in Heroes of the Storm will be granted the new Primal Flamesaber mount in WoW. The matches need to be played with friends on your Friends List.

Here are the full patch notes, while actual hero changes can be found on the official site:
