I am still unsure on this myself (if I would keep them on or off given the option that is).

The main thing that puts me off at the moment is the fact all jobs have the same combo animation.

I do think that now the actual underlying mechanic is in place, creating more impressive, class/job specific animations (even a change of colour would be a start!) could possibly work really well as that extra bit of visual uniqueness when you aren't wearing JSE.
