Nope.
It had Proficiencies, and they didn't cover the same things, nor did they work in the same way, nor did the game suggest they be used in the same way. I played 2E for the entire edition, so why try to pull the wool over my eyes on this?
Here's a list for god's sake:
Advanced Dungeons & Dragons 2nd Edition - Nonweapon Proficiencies
Where's Athletics or the equivalent? Or Acrobatics, for that matter.
The vast majority of Proficiencies in 2E were basically "craft" or "knowledge" skills, with a handful of hyper-specific physical skills which rely on training (Mountaineering and Tightrope Walking, for example).
Absolutely it is
100% a system's fault if you use the systems as suggested by the rules, and the result is trash. That is what 3E's big problem was.
You don't get to claim "under or over use" when you're
using as directed.
