About PVP and PVE

Hello guys im new here,and i want to ask what raids and dungeons work atm and does the achievement sistem work . I logged few weeks ago and ask in english chat but no answer.. And i didn't know were and who to ask,so im sorry for the annoying questions,but i really dont know were to ask . And about the pvp few weeks ago few ppl from the server told me that for now ,a lot of people are abusing stuff and the pvp is not that good (for now) . I hope i dont look like a total ***** :d i'm just asking cuz i dont know and nobody answers.
Thanks :)
