I completely agree. I'm an "optimizer", in the sense that I love gaining mastery over a system and finding all of the things that stack together that could theoretically be explotied by a character. But that's all just theorycrafting. I would never play a double-smiting Hexblade/Paladin multiclass at the table. I just love brainstorming ideas for characters that I'll never actually play.
Oh, and I'm a forever DM. So even if I wanted to play an OP multiclass character, I'll probably never get the opportunity to. The few characters I have played were a Variant Human Illusionist Wizard, a Satyr Undead Warlock, and Gnome Battle Smith Artificer.
