Very true. I simply see that as a pro, and not a con, and put the onus to address the core problem of some players potentially feeling bad on the DM's shoulders, with creative solutions. I understand that is asking a whole hell of a lot, but I think its worth it.
One thing old school DnD did to address it was to give martials leadership mechanics. While the wizard could destroy an army if he wanted, he lacked mechanics for assembling and leading one well, which were given to a fighter.
The concept of a well-balanced DnD really bothers me. I do not think balance should be a core design goal. The Wish spell is horribly unbalanced, and should be. I think its representation of endless possibilities and horrifying consequences is emblematic of the spirit of the game itself, rooted in the olden days of DnD, when the DM was really doing his absolute best to TPK his party in a more competitive, adversarial, board-game-esque setup.
The lack of balance in the older versions of the game had benefits. A player who wished less engagement with the game mechanics could play a fighter, where someone who wanted a larger amount could play a wizard.
Balance in and of itself is not a problem, but unless done very carefully with a lot of attention paid to how that balance is arrived at, it's just too easy to make everything feel very samey. Like a video game that becomes so well balanced that the awesome laser rifle is a perfectly balanced option against some other guys bow and arrow, making it all start to feel hollow and soulless. Like a fighting game that does not acknowledge that Green Arrow and Wonder Woman really aren't actually in the same league, to be able to fairly fight each other in an immersive way.
Starcraft and Helldivers 2 managed to arrive at a degree of balance that still feels wholesome and maintains distinction, but they're very much the exceptions to the rule. It's such a difficult thing that the vast majority of times its attempted, it results in some sort of failure. Personally, I prefer a different route, where devs simply embrace the inherent imbalance, and allow people to do broken-ass things that might be fun, and allow other options to exist that are just plain bad. I see nothing wrong with this outside of competitive, pvp style genres.
Yeah, made the hair on the back of my neck stand up a little bit. The fridge door would function here as a large lever, and a cat's arm is not particularly sturdy.
