It doesn't really matter. Let it be Vocal against Keyboard-Tammy-Charny, or Synka against Gunnar, etc.
Sorry for the resulting flood, I understand that it's just a bad example, but still)) Vocal in HotA is arguably better than all the others combined, especially on a mirror map. Vamp Lords are allowed, and artillery is one of the top skills due to the cannon and ranged attack, which is a mega-skill.
