For me, I really think they should have left the Charr as enemies. Its not game breaking and no, Anet is not going to change it. I really like the storyline of humans being an endangered species now. It would have made the Charr a really good enemy to fight, despite them being used in GW1. So, I guess for me its more cosmetic with the lore than the actual dynamics of the game. (oh, and Kudos to the guy who did the voice for the Charr - he did a great job bringing them to life).
As for other features, I haven't really paid much attention to the quiver on rangers, so that's kind of minor to me. Although if they put a quiver in, I'm not opposed to it.
However, I would like to be able to put my pet "away". I much preferred the GW1 Ranger to the GW2 Ranger where pets were optional (not mandatory). The kind of characters I like are archers. So I really like the fact that multiple professions have "archer" builds (its making 'choosing a main' difficult). But requiring Rangers to have pets has been disappointing. I would much prefer to play 'my Ranger, my way.'
I also loved the cross-professions of GW1. The variety of options made for some rather unique builds. I would have preferred they'd kept cross-professions.
