The tingling means it’s working!
I think others have addressed this, but the way I would phrase it is not that the problem is that bladelocks don't do as much damage as warriors (they would be overpowered if they did), but that they don't do as much damage as warlocks.
This. Warlocks are decent in combat (assuming Eldritch Blast). But they excel at noncombat and exploration. Even a first level Warlock can cast two Charm Person spells every hour. Given enough time, whoever you've captured is going to roll a 1 on that saving throw and become your best friend. The Patron spells (Sleep, in particular) are amazing, especially when you factor in that they're always cast at max spell level.
Also, remember that "short rest" doesn't necessarily mean "stationary." Warlocks are a Charisma class; surely they can convince the party to invest in a wagon (and someone else to drive it).
Lastly: invocations. Mask of Many Faces is fabulous, especially when combined with the Actor feat. For a laugh, foster infighting (literal or political) by casting the Friends cantrip while disguised as your favorite enemy. If you must get an Eldritch Blast cantrip, consider Repelling Blast instead of Agonizing. Sure, Agonizing gets you more damage. That's boring. Repelling Blast lets you bust grapples, knock targets into hazards (like your Cloud of Daggers or Hunger of Hadar), or even knock friends out of harm's way. If you have a pal with Polearm Master, you'll be his best friend.
Yes, the Warlock can be played as a archer with an eldritch bow. But if you want to play an archer with some magical tricks... play a Ranger. The Warlock is so much more.
I will note that warlocks have spells that are useful in interaction and exploration too--not just combat. So those rests can really help out. Is your DM aware of the assumed number of short rests per long rest? If I didn't know it, I'd like my players to inform me of it, particularly if it was relevant to a class someone was playing. The DM might be willing to change the class, change the length of a short rest, or just handwave short rests and say you are assumed to have the benefit of them whenever you enter non-combat situation.
