Alternatively I do think that a good-aligned paladin could still fit into the game. Minthara is likely to be exclusive to the Absolute path, or at least exclusive to destroying the grove, which a lot of players aren't going to want to do. So I think given that, doubling up would be forgivable. A dwarven paladin or monk would be my ideal in that case.
Minthara is paladin class (however shocking it is). I doubt we'll get a second paladin.
But I agree there should be some way to spare her if we decide to wipe out the goblins. This one companion immediately deprives us of two others, and it is not even possible to immediately accept her into the party. In addition, we will lose a bunch of characters (and probably quests and items) that we would otherwise have met in Bladur's Gate. As pleasant as sex with drow women is, she seriously asks a little too much in return. It's not a good deal, it is not convenient for us.
It's actually ironic because the bad guys should get a better deal, but remorse.
You you misunderstand me. I fully don't expect her requirements to change from EA and I don't want them to. They've already said in Panel from Hell 9 that at least Jaheira (probably Minsc as well, it wasn't quite clear) can be an enemy if you go evil, which makes perfect sense. As it stands now it really doesn't make sense for her to join you if you're not all in on the Absolute, or at least appearing to be. I approve of the bad guy route costing a lot honestly. I think frankly think it's too common for evil to be presented as just better and easier. I support subcerting that and having the evil path be painful and punishing while the rewards of being good are actually greater.
Also I really think Minthara should actually be a paladin of conquest. That oath suits her and the absolute so perfectly it's almost sad that she's not one.
