Oh man, you want the real answer?

The people who run these kinds of companies ascended to their roles through a mixture of amorality, naked ambition, willingness to do whatever it takes to ingratiate themselves to those above them, credit stealing, blame shifting, and sabotage of rivals. As a rule, they are uncreative, unintelligent, and cowardly, but they have arrogance in spades. If you think you’ve met an exception to the rule, you’re either wrong or they just haven’t been pushed out yet. Natural sociopaths are common, but so are those who have intentionally become sociopathic in the pursuit of power. It’s a trait that’s selected for.

They will replace successful leaders with their own cronies and yes people because they would rather suffocate a successful thing they don’t control completely than tolerate success from someone that’s threatening to their ego.

For all of their performative hand wringing about layoffs, they don’t actually care and will say terrible things in private.

Long story short, they’re all Carter Burke from Aliens, but the more power one accumulates, the more of an asshole they become.

I agree. I think both should be completely redesigned from the ground up, but they’re not interested in doing that in 6E.

• Wizards should be boosted in early levels and nerfed in later ones, and should be split into multiple classes focused around illusion, commanding undead, AoE damage, control, buff/debuff, etc. (but not all of them simultaneously).
• Fighters should get maneuvers and cleave damage focusing on one or few targets.
• Rogues can continue occupying their niche of single target, high risk / high reward critical damage (but note key phase: high risk). Etc.

Everyone should have a clear specialization with a little overlap. A class should be the best at a thing and adequate at something else.

Yes, OK, two sessions, maybe three since wizards level slower. In AD&D your GM should be awarding for good ideas, role play, encouragement of other players, etc. though, as well as enemies slain. And it’s common to be a little generous with XP in those first sessions.

There was a reason wizards carried daggers and slings as well in early levels.

I just get tired of magic users complaining that they need to do equal damage to fighters from the beginning at range and also be able to warp reality in higher levels.

Exactly, the single session where wizards are level 1 in an inaugural battle that likely lasts 2-3 rounds
