I really like Achievements. They usually give you reasons to go outside your comfort zone or encourage another playthrough.
Obviously, they're not for everyone, but I think it'd be cool if they were in but with a couple of options such as turning them completely off or turning off achievement notifications, etc.
I think it's silly to act like they're antithetical to cRPGs, because there have always been achievement-esque trackers in these kinds of games. Largest amount of damage done, toughest enemy killed, even the notion of gathering XP to gain a 'level' is kind of an achievement. Just because you get a little box that alerts you of completing your already arbitrary challenge, that doesn't somehow cheapen or demean it.
Don't be a bunch of grumpy guses, basically.
