Not sure, I was too busy killing the other faction 馃槢
I didnt pay too much attention to professions, the few I saw were standard 'alchemy', 'skinning' that sort of thing. I dont think you'd use them very often.
Well theres a bunch of different types of quests, you have standard quests, public quests and battlefields. I dont know if they have instances or anything yet.
Standard quests are suited for the context of the game, so whereas in WoW you might go kill 10 deers, in this one you might go kill 10 soldiers. So its the same kind of kill-count quest, but it feels like you're taking part in war, not going off on some redundant quest to get a bit of xp. Also standard quests match your race, so for me being Chaos I had a few where I had to go hunt someone hiding in a cave, get his head, and stick it on a pole outside. Theres other small ones like setting houses on fire or stealing treasure chests etc.
Public quests you just come across, they're scattered about the map. You dont need a party or anything, it'll just say 'Public Quest Found' and you're basically playing. The first one I came across was a few sorcerers trying to summon a demon, and part 1 was to kill 25 militia men who spawned and tried to shoot them to stop them summoning it. When you kill them, part 2 is to collect souls or something from tombstones that appeared, while you are trying to do this, soldiers spawn and attack you. Part 3 a good guy mage appeared and messed up the summoning, and they summoned the wrong demon which killed them and killed the mage. Then it starts to attack you so everyone pitches in to kill it. At the end, it works out how much you contributed to the quest (how many men you killed, souls collected etc) and gives you bonuses and stuff, then it rolls a random number to see how you placed (I came first in score, but the roll made me last). This is so everyone has a fair chance at winning a prize, the top 6 players get a prize.
Battlefields are kinda like King of the Hill, you have a 'flag' to defend, and while its in your hold, it spawns npcs to help you fight. The other team attacks you and tries to get the flag for themselves. This is the PvP part since its mostly people vs people.
