Probably been said, but DS4 needs to go back to being a dungeon siege game... you know... the games that started the series. Dungeon Siege is defined as a party-based action RPG. Replay the games 1 and 2. Those are the games that define dungeon siege. I'm not against the style of game that dungeon siege 3 is. In fact I love them. But dungeon siege is so much more. Its awesome to have 5 or 6 party members, all of different archetypes mowing their way through hordes of enemies. Archers and mages attacking/casting from a distance, sword and boarders tanking up close, melee DDs slashing away, healers buffing and healing comrades... c'mon, it's just epic. And you're in control of it all. It's like an MMO with you in control.
I think DS3 was simplified for consoles, but I would like to think there's enough ingenuity and creativity at obsidian that they could bring the full party back to DS4. And if that's just not possible to do on consoles, I hate to say it, but make it for PC only and do a different hack n slash game for consoles. We can't lose games like DS1 and 2, they're too important for the human race.
Don't focus so much on dialogue and quest text, just some simple exchange of words and onto more killing.
