Does anyone remember when Blizzard said it wanted to add Animal Crossing-style fishing to WoW? What about the idea of a more personalized daily experience for the Molten Front? MMOs are great, but console games still offer a few things that could add some additional depth to genre, and Blizzard already knows this.
Personally, I'd love to see combat get revamped to be more like Monster Hunter. Dodges and attacks are based on real skill, not arbitrary stats (though damage taken and received is still stat-based), plus enemies have specific parts you can hit to eventually break or cut off pieces of a creature. I mean really, wouldn't it be cool if a whole raid focus fired on Nefarion's neck in order to chop his head off and haul it back to Orgrimmar?
Or what about random power-ups appearing, à la Mario Kart or Super Smash Bros.? You're just running around the game world, and suddenly a giant sword appears, increasing your damage dealt by 1,000% and giving you a single move that constantly fires up for 15 seconds. Take that, murloc scum!
What kinds of console-like features would you like to see Blizzard implement in WoW? Enemies that can be knocked out and dragged? Randomly appearing pipes to secret treasure caves? Open-world, mounted combat?
