In addition to everything getting more ranks there are some new skills up, 2 1 point traits (new golds) and some new skills. All 3/3 skills now have ranks up to 8 so 4/4 plus 4 points possible from relics (new relic slot?). Everyone also has infinite (PH) 1% dps increase. Possibly the new paragon. Keep in mind the 0's are just placeholder. Also keep in mind that the current thought is that paragon traits are going to get refunded in 7.2 to spend on new ranks/nodes so pooling AP isn't necessary.

My opinions
BM, WotC cemented as the 1st tier talent choice with 2 new moves empowering cobra shot. Thunder slash potentially moves the legendary bracers up list, at the very least adds more dps to an already good CD.
MM Good single target DPS increase, without knowing what opportunist does it seems like MM is getting ST damage and sort of sliding back on AoE.
SV- First skill is just sweet. Hope it gets a good visual. Get the potential for some massive high damage mongoose strike streaks, probably still the single target king for hunters. Too bad there's a general ranged dps shortage :P
