Nostalrius Begins - Quality wow vanilla realm (1.12)

Are warlock a capable CC class such as the hunter, mage, or rogue in 5 man dungeons? Will seduce work for humanoid pulls? Fear is too dangerous correct?

Fear is only as dangerous as you let it be, if you know how it works it's a great CC tool, especially once they fix the recklessness bug.

Seduce is as reliable as a polymorph, gotta be on top of it though.
