OK, even given all that, it strikes me that the warlock is actually kind of weak. None of his abilities seem to get anywhere near to being as useful or versatile as spells that a wizard or sorcerer of equal level have access to.
Well, the stuff he can do that imitates a sorc/wiz spell is actually pretty competitive with the actual spells--chilling tentacles, for instance, is actually better than EBT since it also deals the cold damage as well (of course, the warlock doesn't get that until a few levels after the other guy get EBT, but that's rather beside the point at hand).
But yes, it's true the warlock is not powerful in any sense of the word. However, an ability doesn't have to be powerful to be disruptive to gameplay. In fact, think about it: when you aren't among the powerful, you sort of have an increased incentive to figure out ways to stretch your abilities as far as possible if you ever want to have your moment in the spotlight. Ozmar's D-door example is pretty exemplary of what we're talking about.
Understand, I don't condemn players of the warlock for doing the stuff a lot of them do that annoys others. I think the class's design basically paints them into a corner. Certainly there can be a fine line between creativity and exploitation (generally speaking, it's creative when you surprise everyone, it's exploitive when everyone knows you're doing to do it for the umpteenth time).
A thought occurred to me: when it comes to resource expenditure, what about the fighter? His abilities are, essentially, unlimited in use, though usable only in specific situations (combat, of course). The resources he has - hit points, ammunition, etc. - are elements shared by other classes. How does the warlock and his abilities differ from this? Not arguing; I'm genuinely curious about the warlock's potential.
Well, if you're asking me, then I'd say Rich Baker's theory about combat rounds obviating the need to count spells per day holds up as long as you stick to abilities of an aggressive nature. If you're attacking people, you're in combat rounds (or soon will be). Once you're out of targets, you're effectively spent. Likewise, I wouldn't make any bones about the warlock's eldritch blast (without blast effects, it's about the same as firing a wand of scorching ray of equivalent level anyway). It's the invocations with out-of-combat applications that I am leary of.
I'd also say the fighter's hit points are a significant drain on party resources. He has more, therefore he needs more healing. And if the party's doing things right, he's the one getting banged on.
