It really depends on how reliably you can get short rests. If you don't get them that often, you are often stuck with eldritch blast spam, a few free spells from invocations (provided they don't require spell slot use) and your two actual spells. We had a few warlocks early, but now they are "the class you dip into" a few levels and then switch to paladin or sorcerer.Different perspectives, I guess. Warlock is one of the most played classes at our tables.
Limitations are inherently fun, to my mind, because they push you to play differently. Warlock would be less fun if it more slots, even if it was more powerful as a result.
