My predictions are:
DNC and GNB showed
DNC is stupidly broken and very fun, and will most likely become so bad that it's unplayable at 5.1 (Heavensward launch AST)
GNB is quite balanced and fun
They repeat what they said about genderlocks
They showcase new glamours
They showcase new mounts
They show WHM and its even worse
SCH is also bad now
AST is broken
MCH is a lot less fun but a bit easier to play
DRK is quite fun and balanced
They showcase all of the other jobs
No benchmark at all or not until the launch of ShB
