When Miyomoto Musashi was late to his duel with Kojiro, the Demon of the Western Provinces, and then slew Kojiro with a carved oar that was slightly longer then Kojiro's legendary very large sword, some thought that gauche.you can make a cheese hexblade that is still an EB AB Hex type but... then why be a hexblade). But to be able to perform well in that role, almost all their invocations will be liked to their fighting... so your "bag of tricks", the endless at will abilities, is preeeety shallow.
I'm a bit obsessed about this class. I know that a hexblade multiclass can be a very strong build, but I really would like to play it single class. But... I have issues.
The Hexblade seems to be, on the surface, the classical "Gish" - the fighter/mage that blends swordplay and sorcery to win the day.

aaaaaand with the hexblade it doesn't seem to quite work,
..snip...
I guess you could build an EB based hexblade... but that's more of a hexcheese really). Furthermore, it is easier to build them with a few more utility invocations.
So... what to do without multiclassing?
I have three things for you. (I know it is a wall of text but I assure you it does contain options and serious feedback. I am not concise in my attempt to cover it all but I know there is chance no on will read it. Sorry.)
1. Your last thought is correct, the Hexblade is actually better as a pact of tome or pact of chain eldritch blast build.
2. Its often thought of as cheese, but it really is a solid way to play a warlock. Hiding in Darkness with Devils sight, gives advantage on attacks for offense and Opponents disadvantage on attacks against you for defense based on "Unseen Attackers and Targets" PHB p194-195). Wizards double downed on this with level 4 warlock only spell Shadow of Moil from Xanathar's Guide to Everything which is and improved version of this without the requirement for Devil's sight to free up an invocation. Using your first spell slot to activate this in combat and your second as a backup incase you are hit and fail your concentration save.
I never thought of it that way.3. I am on board with making a "Gish" warlock but I ran across the same issues. I ended up making a homebrew to get a subclass that would fix the issue I had. Part of the problem is that warlocks are Multi-attribute dependent and need access heavy armor proficiency for Ring Mail to mitigate that, every warlock subclass to date has a defensive ability at level 6 because they are the only caster class that can't use spells reliably for defense.
snip
but the level 6 defense abilities don't have but one charge up front, don't recover on short rests, and/or don't scale for greater defense at higher levels the way other casters getting higher spell slots and more defensive spell options can.
Been there, done that but with an eldrich knight built - more spells, more cantrips, more gish... Adding to that last point, if you do multi-class to make your Gish work with Ring mail, Cha and Constitution, I recommend the Fighter subclass Battle master, because the Superiority Dice also restore on short rest. Then assuming your GM actually uses short rests and multiple encounter days some times you will have a bit more to help you be the team anchor when your party expect you to with Evasive Footwork and Parry.
Your welcome.-snip-

Parry, as does the rune knight with the hill giant rune, pairs really well with armor of agathys.
It's so sad when players feel characters need to be absolutely optimised. They miss out on so much.I know and it bothers me so much....

Good enough is good enough.I don't feel the have to optimized but I do like to be good as something.
A character with medium armour and shield proficiency, and d8 HD (along with a bunch of other defensive tricks) does not have "crap defence". Not as good as someone else does not equal "crap". And they are not going to die.hard to play a melee character with crap defense
Good enough is good enough.
The trouble with optimisers is binary thinking. Anything that isn't the absolute top is garbage.
