Funny; that's what the DM thought too as I was robbing his creatures of actions, occasionally tugging on a puppet's strings for kicks, and quietly spreading 100+ of multi-keyword damage around the board. Of course that wasn't a pure Feylock, but that was the idea
Oh, and my party loved it when I used Mire the Mind.
So you were playing a high level Warlock with multiple encounter powers and dailies. Right. But we're talking about Eyebite, not the whole warlock package - Warlocks don't have the whole package for quite a few levels to come.
To quote myself a few posts up
The core problem with that defence of Eyebite is that At Wills are most needed at low levels. The levels where you have only one or two encounter powers and one daily. As a Warlock, your other At Will is the frankly sucky Eldritch Bolt - weak damage, no control and poor at low levels when you are likely to be facing lots of kobolds and goblins. Eldritch Bolt has the approximate accuracy and damage of a longbow RBA with absolutely no control.
Over the first two levels, something like 75% of your attacks are going to be At Wills; this is where the power of the at wills is most important. And Eyebite might set a few things up (and I'm certainly not ragging on the Feylock as a whole) - but with only one encounter you have almost nothing to set up. Its use for setting things up is therefore negligable.
Eldritch Bolt compares unfavourably with just about every other RBA implement power in the game (with the arguable exception of Magic Missile) especially at low levels where reflex not fort is the high defence and RBA attacks compare unfavourably to normal At Wills. And Eyebite is a nice combo spell, or would be if the Warlock had anything to combo it with most of the time (one encounter power - which might be a very nice one but is still just one power and the daily is ... daily).
When your only powers are Eldritch Blast (poor) and Eyebite (poor unless you have support for it/something for it to support), this means that you are going to be making a poor attack. This means that 75% of Feylock attacks across the first two levels are going to be poor. I'd call that a fundamentally negative play experience at the time when it most matters. And this is why Eyebite needs sprucing up (and Eldritch Blast needs fixing).
Drop a Pact Weapon on the Feylock and things change a lot. They now have an At Will that actually does damage and can be their main attack power. And they have something that combos with Eyebite - eyebite and walk up to someone invisibly with the feyblade and they are in a messy situation as attacking you is a mistake and you're threatening them with an opportunity attack if they try to get away. Eyebite can be effective if you have something decent to combo it with - but there's no point supporting Eldritch Blast (Eldritch Strike is a little better but not in the PHB). And the Feyblade therefore becomes a feat tax at the levels where you have no feats to spare.
