depends on what server. on Klaipeda, i usually only see people on West Silulai Woods, East Sililuali Woods, Miners Village, and Nefritas Cliff/Strautus Gorge/Tentans farm. As well as Tenet church (although some are bots). the other maps are pretty dry i dont see many people on those maps.
you dont really use the market until youre 300+ really because most of the gear you get on the Market is worthless (other than the 270+ gear with some exceptions). And you also need a token to to be able to effectively make use of the market and team storage. and Tokens in Klai are 4.6mill Atm, really high. you an get a Practonium for that price in Silute. Tokens are also going scarce. Good thing is theyre dropping price, they used to be 2 mill, then they raised to 6 mill in less than a week, now theyre slowly making their way down.
also with the new patch and DPK removal the prices in the market will drop as it will bea easier to farm stuff, they havent dropped yet but will soon
