30 years of 1e experience tells me to disagree here.Really, in the early days of the game, it seemed like the eventual dominance of casters was not only obvious, expected and inevitable, but was actually a design feature.
'Balance,' was considered across a character's adventuring career. If you were comically weak at 1st level, that balanced you being wildly powerful at 18th. [...]
Those old balancing mechanisms only worked as intended (leaving aside whether working as intended was really balanced or not), if you played long campaigns which featured random character generation and disallowed changing characters, starting at 1st level and progressing well into higher levels.
We use a generous character creation method - the same for all characters - and allow characters to enter and leave pretty much at the players' whim. We've also removed just about all the race-class restrictions.Obviously, a lot of campaigns were short or used generous character generation variants or started above 1st level, or allowed characters to be swapped out at a given level.
It's not Monopoly if the boat and the shoe play the same.It's like a game of Monopoly where you start with 1/4 money but can purchase property without actually spending money.
