For me I am hoping that we get more physical options in Character Customisation (Hair, Face, Hair Colour, Voice?, Accessories like Piercings, tattoos etc) as well as options to define Body shape (Human comes to mind)

In terms of Racial abilities, well, Elves take the cake here, Corpse Eater and Flesh Sacrifice are two awesome abilities in terms of Lore and Combat, my issue (and this is the same for all races, except Human) is that the +2 of a certain stat really pigeonholes you into that archetype and even if you want to multispec you can't really keep that up (As far as I know and that is a different topic all together).

For Human, I really like the +2 Wits and 3% crit chance as it is a solid boost without the fixation on an archetype (You could always get Savage Sortilege to benefit from that extra crit chance if you are a mage type character)
but the +1 Leadership is kinda lackluster. Maybe make Encourage available to all races through Warfare (seeing how it will guarantee to work regardless of whether you are strength based or not (I LOVE using Rage because of this with Rangers and, because of Savage Sortilege, Mages) but a Human using Encourage would be enhanced, like say breaking allies out of certain CC/reducing the chance of succumbing to certain CC

Unsure about Dwarves and Lizards, not really given them too much thought as of yet
