To begin with I almost wish we did the same thing with Warlocks as we do with ECL races, which is to say, restrict them. I'm just waiting for the DMs to one day take advantage of the fact there are so many of somethign that is suposed to be rare, and maybe do a quest where a Demon or Devil rips its way into Sundren from all the built up dark eldric power that is spread around by the Warlocks.
As for a reason for the evil or chaotic alignment look at it this way. People arn't just sending out these eldric blasts, which generaly have an origanal source from the lower planes, but they also training themselves to bring out these powers even more. Considering most beliefs of those who would willingly weild powers like those one is essentialy going about doing whatever they are doing in thier own way (aka chaotic.).
I'm not really sure what kind of rational a non chaotic character might have for training such powers if they are not evil other then to control them so they don't hurt anyone, in which case only one level would really be needed. (if even that)
