Here's a few tips I can think of, listen up anons:
Pick up EVERYTHING, you will need them for quests, and whatever surplus you get can go to your alts.
Disassemble blue gear, sell white gear, you can try selling the purples in auction, or just disassemble them too, same for pinks but these usually sell for something. Player disassemblers over level 4 give out more cubes up compared to the machine.
Read up on current events, most are as piss easy as logging in for a certain time and give out great stuff, frequently including good cash shop items and avatars.
Fatigue potions and EXP potions; Use fatigue ones only after you've completely exhausted your bar, and EXP potions only at the very end of the dungeon as they only increase the clear experience.
If you can, join a guild for passive stat/exp increases (I don't care, personally, but it's there).
Make alts, if you see a character that looks like your thing, make it and level it. Alts give account-wide stat increases, you can send those you don't play out as mercenaries for free items, and call alts in as strikers mid-dungeon. Also a good way to keep playing if you're out of Fatigue.
Storyline feat quests give titles, and every few ones you get title book upgrades for minor stats, so do those for sure.
Do not bother with gear or money until you're maxed out which should take 1 or 2 weeks currently. The stuff you get from quests is enough to rush you to the finish no problem.
Professions (Alchemy, disassembly, etc) are a money sink and usually not worth it. Only after a very long time will they start making your money back. If you can, learn one and don't bother actually using it, just to get it out of the way.
You can "disable" all chats by going windowed (full) and setting your chat to the right or left side of the screen, so it goes off your monitor. Echos are mostly shit.
As an early money boost tip, your arad meteors can be traded for 15-meteor pinks with Albert in the Sewers/Meltdown area. When you stop dropping green meteors, go there and trade them all for those pinks, then disassemble them for plenty crystals which you can sell for a decent ammount on the auction.
