The trouble with fighters IMO is that armor is just plain less useless than grabbing Dex. The former can get bypassed by certain attacks and also costs money, the latter is free and does not get bypassed. It also lets you roll Dex saves to avoid AoE, which is something armor can't help against. So if you go for Str you're just plain worse than a Barb who gets to rage and use those temp HP and DR to tank damage, and you're pretty much just a money sink as you try to scrape up the money to get platemail. Meanwhile a ranged fighter that stacks on Dex can do a surprising amount of pain with a Rapier/shortsword combo up close and a bow from afar, and with the proper feats you'll be doing crazy damage. Crossbow Expert, Sharpshooter, and a Heavy Crossbow lets you nail guys out to 400 with no Disadvantage for 1d10 piercing, and you get to make as many attacks as you normally do, so at level 8 you're popping off 2 1d10 attacks with every single Attack action... and at anything you can see within 400 yards with no penalty, and you ignore anything short of full cover, and in 5e ranged weapons get to add their ability score so its not terrible. Considering 500 is about what a current-day designated marksman is capable of with a 7.62 rifle, that's pretty damn good. Oh, and unlike a Rogue or Ranger you have the HP to get into melee if necessary and not die horribly.
Granted, I can't exactly say its good to be a fighter, but you can do whatever combat job is necessary in a pinch... if you snag dex. Otherwise you're just a worse barb who needs armor.
Of course, that's my 5e experience talking, so I can't say what its like for other editions.
(I can go on and on about the utter uselessness of Str for fighters, but I'll leave you with the abbreviated version above.)
Yeah, I realized that my mail armor wearing fighter would be better off wearing a breastplate would mean he retains the same AC that he has now, but loses the disadvantage for stealth checks. So even as a strength-based fighter, dex is still more useful.
I thought that Strength would give me an edge when I wrestle with someone, but apparently, putting someone in a headlock does jack shit to their ability to fight, no matter how strong I am.
Overall, me being unfamiliar with DnD 5e rules before making a character, learned the hard way that strength based fighters with champion are boring to play and severely limited in what they can do outside of combat.
As a result, I have realized that I am barely involved in anything the group has done for the past months of (admittedly irreuglarly scheduled) sessions - which is partially my fault, but I just don't get invested into what's going on. I sort of tuned out with some of the inter-personel roleplay with NPCs and it's hard to get back into it. I guess you could also call it DnD fatigue, since I I am unhappy with the way how DnD handles certain key aspects of its gameplay, so even fights have become mind numbingly boring in general (infuriating at worst), which is ironic when you consider that that's the only thing my character is really good at.
I considered multiclassing to spice things up, but it feels like that would take too long to bear fruit and in the meantime the one thing I am useful for stagnates. The leveling system feels like the character has no personality at all and no genuine way to branch out without multiclassing.
On a sidenote: A pet peeve of mine regarding DnD is how everything boils down to how effectively a character class does the powercreep. Ranger is considered the worst class and maybe I'm wrong about it, but it feels like it's considered a shitty class cause it's progression/powerlevel doesn't make that thing a nuke on legs at a certain level, that's finetuned to fuck shit up with impunity.
Dude has a bunch of useful abilities and spells, but they're not exclusive enough and not damaging/strong enough, apparently.
Goodberry can be a godsend to keep your party alive. Alarm seems very useful. Ensnaring strike, searing smite or snare seem handy, too.
I guess I'm just too used to low-power RPGs, where all these spells would come to good use every once in a while.
