How fast are you looking to clear content? cause that's the important part...

There really isn't a huge difference between different compositions (within reason ofc), and while that could be the difference between world first and world second kill maybe, it matters less and less with every week after the patch.

For A1-A4 Savage, the composition doesn't really matter anymore. With the gear you should have now, the relatively small differences in DPS, are not gonna mean anything if you play your job the right way. Of course, if you struggle with getting the most out of your parties jobs, then going for a more optimized setup is gonna help. It's not gonna magically be miles better though or anything.
