One other thing I've noticed. The practiced invoker feat for warlocks does apply up to four levels to the invoker level (which it should), but it also unlocks higher level invocations earlier (which it shouldn't).
A long time ago (under the previous management), I was asked about the warlock prestige classes. Both eldritch disciple and eldritch theurge are only ten level classes. It might be nice to make them have an epic progression, like mystic theurge has. Also, I believe someone else suggested removing the turn undead prereq for eldritch disciple. The class requires turn undead but then gives turn undead at the first level, at least according to the description. If this is so, it would be nice to not require it to enter the class. There are some intriguing build possibilities involving classes like archivist and favored soul. The problem with eldritch disciple as it currently exists is that it depends upon too many different abilities. Wisdom is something a warlock can do without, but obviously a cleric can't. Being able to use a divine class that had charisma or intelligence as its spellcasting stat would make eldritch disciple more viable. Alternatively, if there were a feat divine spellcasters could take to get turn undead (and qualify for eldritch disciple), that would also work, though I'm not sure there is such a feat in PNP. I doubt it would be hard to code, though.
On the subject of warlock prestige classes, I've also become aware of an eldritch shadow prestige class (warlock-rogue blend). That would be cool, too, if anyone had time to make it.
