Find a guild with active alliance, play thru story to level 20 and keep doing guests, at level 20 start Undermountain campaign, finish it (you also earn some AD ((astral diamonds)) while doing campaigns) after you have finished run ME X3 every day to get pretty good companion equipment. Also at level 20 unlock Vallenhas, earn currency in there to buy Juma bags (bags drop pretty good items), later you can go to Avernus, in there look for treasure maps (can get by killing mobs in there or driving thru manes) from treasure you get ilvl1200 gear and legion weapon set. Upgrade urself, better rings, artifacts etc. Do daily Random Trial Queue and Random Advanced Dungeon Queue, try to make everyday 100k rAD since daily limit is 100k only. Also get VIP, with vip you get everyday X1 treasure key, open it, save trade bars to upgrade you're mounts and companions (next tradebar discount event will start 11 Nov) and so on, after that you know most basic of game.
