Believe it or not but some people actually loved playing Bard. And I actually liked the job variety in FFXI since the jobs all felt different. In FFXIV the jobs just all feel the same, it feels boring.

Most MMOs have a support/buffer job and there are players who enjoy playing these classes.

You are of course entitled to your own opinion, but there are people out there who loved all the distinctly different jobs in FFXI and who love playing support classes.
