I'm also hoping they phase out classes by 2.0, it's unnecessarily convoluted.

The counter-argument seems to be "There are still things classes can do than jobs cannot", but if you remove the current cross-class limitations of jobs, can you still say that? If PLD had access to all the same skills as GLA, would you ever use GLA again?

No, and that's how it should be I think. Classes and their job counterparts are so similar that there is no need to have both. Sometimes less is more, and streamlining the battle classes to just PLD, WAR, DRG, MNK, BRD, WHM and BLM by 2.0 will certainly make things less confusing for new players.
