Yeah quest credit and shit is like old school too, no sharing, whoever tags it first(and it's almost always a fucking archer) gets credit. On the upside respawns are like super fast. There's also generally a lot of alternative spawns, it's less theme parky than wow quests, or I should say the kill quests aren't as specific and crafted in detail, so it's like "kill this type of bandits" and then you get into an area where it's just those bandits in a fairly large area(but in small camps, so if you camp somewhere and there's 3people and you stay there it sucks dicks, but if you mount up and run around for 15secs you'll find more camps).
Quest givers certainly have the !. They even have a fucking beam of light coming down on them so you can spot them from far away easily. Quests are absolutely shit too, like there's a "story" questline that tells some weird ass story with non subbed non dubbed still drawings, a bit like GW2 style stuff but other than that it's the bare minimum, guy asks you to go kill 8 kobolds and that's about it. However you don't get like 50quests, generally each hub literally has 2 to 3 quests, the story quest that showed you the hub(which might or might not have a quest in the area, otherwise it sends you to next hub right away) and 2 basic quests in the area, one of which involves killing shit and the other collecting shit, and they're sometimes done both at the same time(collect these items that also drop on the mobs). It's very much directed grinding with a bonus for doing it, like old wow. Grinding mobs seems relatively viable, quests don't give that much xp and you travel quite a lot, but I haven't tested for sure. I wanted to do the dungeon too but haven't had a chance.
The quests complete fast though, TTK is fast, distance from the camp to the quest area is generally short and amount of mobs required is so far pretty low but if you overachieve the quests then it gets more traditional numbers. Like the most I've had to kill atm was 8 and it's quite often 6 instead, but with overachieve that becomes 9 to 12, matter of taste, since I like the combat I generally do it. So there's a good flow to it, at least what I've played(I'm 24 or so). You get levels fast too so that helps.
