In an attempt to avoid thread necromancy, I will thank you for the elemental based ones here. I have been trying work on an elemental based invoker (that came with an elemental pet), so that will help me.

As for these, they seem interesting, and as I am planning to run a warlock soon I shall see if my DM would allow any of these or the other ones. I only took a quick glance at them, so I will have to read through them more in order to give input on them.
