I just started playing my first warlock PC (and the first time anyone has run one in a game I've played).
Started at 3rd level (joined an existing group).
I did multiclass ranger 1/warlock 2 for themeatic purposes. Favored enemy - evil outsiders. Theme - demon hunter alignment c.g.
The 2 least invocations - eldritch spear and devil's sight (DM treats darkness as darkness not shadowy illumination)
He as so far been subpar in combat. The paladin and vow of poverty monk (still waiting for him to get his clock cleaned since he can't take the toe-to-toe damage as well) still deal the majority of damage.
Just gained a level and today I get to try him with the the 2d6 eldritch blast.
IMO at mid-levels the eldritch blast damage might be seen as too powerful - but in general it only affects a single target and can be used only once per round. Multi-attacking front line combatants do consistently more damgage. Don't forget the soft cover rules for trying to blast a foe when he's engaged in combat with an ally. {I took point blank and then precise shot to mitigate this - but you can see how many feats I've had to spend to be "useful"} A mid-level wizard does more damage with a fireball to more combatants than a warlock can. 5th level wizard does 5d6 (save for half) to all within a 20 ft radius.
Something else to keep in mind is that there are relatively few decent prestige classes that a warlock can qualify for since they don't cast spells of certain levels.
