A little bit more content to your assertion, perhaps?
Actually, WotC clearly hates warlocks, but it hates the feylock even more than the other warlocks. How come the rogue gets a paragon path that increases the crit range of all its powers and the warlocks paragon paths increase it on powers with rare keywords? How come the rogue and ranger get to improve their extra damage dice and the 'lock doesn't? The sorcerer gets a bonus on every single damage roll regardless of how many targets or when in the round the target takes the damage; the 'lock gets bonus damage once per round, period. The warlock is supposed to be striker but sucks against solos because they do crappy damage but have rider effects against which solos save 80% of the time.
As for why the feylock sucks even worse than the other 'locks:
first level enounters: all do multiple dice of damage and have rider effects except for the feylock one which does one die of damage. The "bonus" you get for being fey pact is that the range is 10...but all the other powers have a range 10 for free.
Level one dailies: the powers that use Cha are weaker then the ones that use con.
Encounter 3: not bad, except that the range is again 5, something that almost no warlock power has had up until this point.
Daily 5: here the cha powers are better than the con powers. I am shocked
daily 9: terrible damage for the fey powers with useless riders (ooh, i can end the damage and slide the target? really??)
daily 15: huh, there isn't even a new power here for the feylock. too bad
that's as far as I have gotten. Oh, and the coolest thing about the feylock, the teleporting? every single class in PHB2 except the barbarian now has more and better teleporting effects.
