Most classes have or had a second weapon anyway (Gla had Swd + Dag, etc). I get that it wouldn't be efficient when each GC offers a different level 40 and 50 weapon for every single job, but if they spread them out more, it wouldn't be so bad. 20-24 different types of weapons doesn't HAVE to be too many... Ifrit wouldnt have to drop one for each job.
Anyway, that idea has been dismissed and dissolved long ago. Just felt like reminiscing.
