...that Elminster only shows up AFTER the quest is complete, and the bad guys are dead? And then proceeded to handle the "difficult" stuff?
'Scuse me, but...uh...how about showing up a few minutes before the boss fight, and helping us in the final fight? You think THAT might get that artifact you so desperately need to defeat Lloth / the Netherese / whatever? Huh? Ya think...?
Likewise, you got into the Demonweb. Maybe a little help with the elementals in the area between the Demonweb and Faerun wouldn't kill you, now would it? You could show up, maybe banish a few of them, and leave without having for Lloth or her psycho sister to get distracted and all. Frankly, I'm getting a little sick if that bearded, know-it-all with his "ye"'s and hit witticisms not pulling his weight in all of this content.
I think the devs need to up the loot in an quest chain that uses Elminster, to compensate players for having to do the dirty work of a full-on slacker.
