Nope! You didn't scare me away. I'm just hugely fucking busy, and as said I don't like checking Codex at work. I'm also a bit more skittish giving answers to GW2 stuff vs. Dead State stuff because if I fuck up and answer something wrong it's not my boss going GODDAMMIT ANNIE, it's just Brian, and I can be like AUGH NOT MY FAULT and stuff, and yeah. Also a lot of times, I just don't know - I'm on one group out of a HUGE FUCKING TEAM (versus Dead State where I can give conclusive answers) and I dislike making presumptions that may be inaccurate. My specific arena of knowledge is the personal story, but this doesn't mean I won't give a stab at answering something else.
BUT BASICALLY. Don't know about player walking anims! I know you run faster when you've got your weapons stowed vs. weapons out and ready, which helps for combat, and I know they're working on a bunch more anims, and there's an NPC walk anim, but I'm not sure how it applies to players just yet - I couldn't say anything right now for certain. I would wager walking will get discussed at a later date, but Jesu Christo, the scale of the cities is so amazingly ginormous I can't imagine wanting a super-leisurely stroll on a regular basis. I sort of just stop and gawk, myself
GW1 had a fuckton of skills, and balancing them could indeed lead to madness. GW2 has it so you can get a great variety of skills, but never inadvertently screw yourself over. With traits and utility skills in the mix, you've got an insane variety, but not so much and balanced in such a way as one is HAX and another build is SUK. It's very approachable, and yet my calculating min-max brain sees the options available and cackles with glee. It's really awesome, and very complex and flexible.
Mangoose! You have many questions. Alas, I was talked out to try some holiday beers tonight (damn you Seattle, having too many rad breweries) and it's a bad idea to answer complex questions when drinking, so I'ma pause on the personality one. As for the Codex, I think many of my co-workers don't have much truck with it, but our lead (Eric Flannum) knows about it, does NOT in fact hate it, but respects it as the hardcore set who know what they want and do not have any compunctions about saying so. When the Codex seems positive towards something, it is usually a sign that there's probably something rad going on there.
