They completely bypass the intended experience of old games. Why would I ever be scared of dying in Super Metroid and going back to the last save when I can just save state before a boss fight? Or, if the emulator allows it, I can even just rewind after every minor mistake.

I know the obvious counterpoint is that you can just not use save states, but their very presence changes how you feel during play. What should be the default experience now feels like a self-imposed challenge, and the temptation to give in and use save states never goes away.

I like emulation overall for how it makes retro games more accessible, but I wish the save state had never been invented.

At high levels, Eldritch Knights get more attacks than Bladesingers as well as more feats, weapon mastery, medium and heavy armor proficiency, and eventually even the ability to cast leveled spells with attack action. You get all of this while also getting the same upgraded cantrips as wizards, essentially benefitting from the main DPS upgrades of both fighter and wizard, so you just end up doing more damage on turns where neither one of you consume resources. All while having significantly more HP.

Addressing some obvious counterarguments:

Wizards get higher level spells. I will concede that Eldritch Knights take much longer to get Fireball and never get Chain Lightning, but I think this ignores the fun aspect of playing a spellblade. The fantasy of a spellblade is mixing up weapon attacks and spellcasting, and if you cast a main action spell in combat, you can't also swing your sword. If you wanted to spam Fireball, you'd rather just play an Evocation Wizard. Your bread and butter reaction spells like Shield and Absorb Elements are available at low level (you can even get them as a level one fighter if you take Magic Initiate as your origin feat), and like I said above, you get the same cantrip progression regardless of class.

Eldritch Knights are MAD. The spells you typically want to use on an Eldritch Knight don't scale off Intelligence. Your Shield raises your AC the same either way, your Misty Step goes the same distance, and even your Cantrip attack can use Strength or Dexterity if you use Booming Blade or Green Flame Blade. Admittedly, your ranged cantrips will be a bit weaker, but you have to remember that Eldritch Knights get more ASI than any other class, so being MAD is less of an issue overall.

You have to Long Rest a lot since you don't get many spell slots. Maybe this is just my table, but I've never really felt like this is that much of a problem. Long Rests in 5.5e are not that uncommon. Plus, you're reasonably durable even when you run out of Shield thanks to armor proficiencies and d10 hit dice, and you'll always have cantrips. Just be conservative. Only Shield if you know it's a big hit, don't bother using leveled evocation spells unless your enemies are extremely bunched up, and remember that you still have your base Fighter features which are overall quite good.
