A little while ago a short thread started on Dragonsfoot about adding multiple attacks for fighters as they advance in levels. The thread specifically focused on BECMI but that is close enough to B/X for me to comment.
The thesis put forward in the thread is that the damage output of fighters is dwarfed by spellcasters in later levels and that by adding extra attacks the fighter can keep up.
I don't think this is necessary. One of the reasons why I love B/X is that the by-the-book rules for spellbooks (whether intentionally written this way or not) is that magic-users and elves may only have as many spells in their spellbook as they are able to cast each day. I believe that this limits spellcasters so that such tweaks are unnecessary. Yes, a couple of times per day they may be able do things the fighter can't but the magic-user's limited resources and versatility keeps the fighter very relevant.
What do you think? Do B/X fighters need "buffing"?
