They just launched a Recruit-A-Friend system for Heroes of the Storm. For the first 5 days you get a free stimpack (boosts your xp and gold earned per game), as well as giving you 2 free heroes. Here's my RAF link, if anyone's interested. If you catch me online we can play some quick matches. I'm usually online on TS while playing HotS, too. Here's the info on the RAF system.
For all you Hots fans out there, check this series out "Beyond the Worlds" Enjoy Episode 1 Episode 2 Episode 3
