But, no it isn't. Since play almost never actually goes past the demi-human limits, those limits are largely not coming up in play.
Are you going to claim that a majority of AD&D games progressed past 12th level?
@
ForeverSlayer - as has been mentioned several times, you are referring to the wrong version of D&D. People were referencing OD&D and 1e D&D. Additionally, while the tables do cut off at 20th, there is nothing preventing you from progressing further. The game was never designed to play from 1 to 20th.
Also note, that in 2e D&D, Magic User Spell progression means that an 11th level elf wizard gets 6th level spells.
Meh, cherry picking examples and ignoring any and all other evidence - such is the stuff edition wars are made of and I'm stepping out of this one. No thanks ladies and gentlemen.
