Helloo, it is totally normal that all maps are empty coz its kinda simple and easy to get trough the levelzones in few days and endgame has its own maps, dungeons and raids. Im mostly sure you will not find again people standing before dungeons or pvping in aseetep like once coz the expgain from pvp there is neglactable. therefor you will have a ton of tasks you can and or have to do in endgamecontent for progress.
You can calculate for your self about Community if you notice that memberlimit of guilds is 150 and 4x6 members are max for weekly guildfight in rankmode and if you are generous assume there are 20 guilds maxing this out but in real only guilds place 1-5 may have full capacity at best each week so you invest in a game with 200 active players you will loose against and prolly few more leeching you in other random content.
as some guys complain about hardcore paytowin and the long and timewasting grind and grouplimitations in mostly all usefull content i can only recommend you bring some friends with you with some that not want play cleric scout warrior or other overpowered classes and have fun as long as you enjoy the classes coz beside some ratracemechanics and oneclassperplayer limitations in ranked guildfights is this game kinda polished and playable smoothly.
ps: i would guess the young turkish players are even in majority (dont know why but the game has made huge efforts to attract little wannabe assassinmegakillers into this game with hilarious oneshotmechanics and awesome killingrewards like devilwings, noisy killanimations and sassy chatmessages
