Actually your poll was for just the last year. Since campaigns can last years, your poll skews things a bitMy current impressions are:
• Fighter is a useful, versatile, enjoyable, and popular class.
• Players use the Fighter class in very different ways.
• There are about as many "old school" nonmagical Fighters as there are Monks.
• A significant segment − roughly 30% − never see this kind of nonmagical Fighter.
Very many? How do you get that from the poll?• The Fighter has already become the magical, "gish", "wuxia", "mythic" warrior for many players.
Certainly, the nonmagical Fighter enjoys popularity − and is iconic − and is appropriate for 50th anniversary edition.
The surprise is, this kind of Fighter is irrelevant for very many players today.
