They might expand the armor system with a coin or coins. That would definitely change how you play almost every hero.
I’m hoping for a new pandaren tribe to hopefully lead into a Pandaria-themed expansion.
I look forward to seeing more of peoples Rogue creations. I'd love to somehow make the Secret package viable. Whirlkick is still miles ahead in Standard, and with the introduction of Nitro, Kingsbane dominates Wild.
I love when they bring lore into these kind of events. Well done.
I can’t wait for Valeera’s storyline. I’ve been a Rogue-only player since World of Warcraft came out in 2004 — the same goes for Hearthstone. I look forward to the Rogue exclusive packs and skin. :-)
