From what you've said here and elsewhere you've implied that
by definition halflings are therefore irrelevant because it is impossible for halflings to be played more than halflings are.
I'm fairly sure you don't think you mean that - but the 5% threshold you set looks as if it was set
after you looked up statistics for halflings and found them just under that
And I look at them and say that's a distortion.
Wasn't it you who dug up the lack of lore in the Realms on halflings and Yolanda? Wasn't it you who dug up just how little they are used in adventures in practice?
Lip service has been paid to giving them advantages - but when it comes down to it neither TSR nor WotC have ever really cared about halflings, and especially not in the biggest setting around. Even
gnomes have a much better deity in the Realms than halflings do. For that matter gnomes
have an actual pantheon of eight deities in the Realms - and yes the halflings have six, but I don't believe the gnomes have ever had the indignity of having their deity demoted to an aspect of someone else - and left with a new chief deity
almost entirely lacking in lore other than this event. And back in the greyhawk days the
Gnomes had far more lore and detail than
Halflings.
Or possibly it's time to give them an actual chance rather than simply saying they are there and that they are common, and stopping there the way the default setting for D&D does.
Short changed, overlooked, and ignored - and still trucking along despite getting mere lip service. It's probably time to actively let halflings have a swing at the bat rather than just send them out into the deep outfield and then complain when they don't hit home runs. The archetype is solid - but nothing's been done with them by TSR or WotC (Eberron being an honourable exception).
