Who actually USES alignment languages? How?

[Daniel D. Fox]

Heh, no.

We didn't use them in old AD&D and we don't use them now. It didn't make a whole helluva 'lot of sense.

weapon vs armor modifiers, weapon speeds, training...alingment language is another one on the pile of little known and less used AD&D mechanics.
