Of course, I suspect it will be akin to the ME 2 version of infiltrator cloaking(just the pessimist in me), and have no other gameplay value apart from direct combat.
To be fair, you couldn't exactly sneak your way through DAO either. DAO was a very combat-centric RPG, much like Baldur's Gate.
I'm not wanting to sneak my way through the game. I don't even think it was possible to make an entire party of rogues in the first game.
I was talking about being able to send my rogue ahead to see exactly where enemies were and setup traps accordingly and prepare my party for an encounter. I like to play that way and I hope that option doesn't go away.
