From a meta standpoint, if you kill Astarion, aren't you kinda forced to make Tav a rogue? I do not like playing the game without a rogue.
In early access, Shadowheart as a trickery cleric with an urchin background can do most non-combat rogue-y things adequately enough, though she's likely to get through more lockpicks given lack of Sleight-of-Hand expertise. And in the full game we'll have the option of multiclassing or even respeccing companions into rogues if we really don't want to do without one. (Personally, I find it quite fun at least sometimes trying to cover the various party functions without using classes they're standardly associated with, but everyone can of course play in whatever way they most enjoy.)
EDIT: As Tuco says, this is a very old thread but also as of patch 9 there hasn't been any significant change. So if people want to discuss it again in the thread, I don't see any harm. I have moved it to the Suggestions & Feedback section, though, on noting that Tuco had suggested that back in his original post but it obviously hadn't been picked up by a moderator at the time.
