Hello! I'm Devilswork! I'm from Brazil (sorry for bad english).
I play HotS since Alpha, but not a hardcore player, and just starting to play hero league just now.
Sonya is for me, the coolest warrior to play, since it has a lot of damage and can be almost an assassin. It's really commom to be the top damage in the game with Sonya.

There's two builds up there, the Mercenaries Solo (BOSS) [to focus solo killing mercenaries, boss and stuff) and PvP Focus [more damage less self heal and protection].

Since i'm doing this Build just how i like to play the heroe, i'm not going to explain and do a talent breakdown. Any doubt please share it in the comments.
