A casual palyer un SSF needs helps.

Hi, I've been playing POE for 5 leagues in trade league. I started a Ranger in SSF without guides and only with the knowledge I've gained so far, which is quite little XD.
What tips do you have for a casual player that I should know?
What should my priorities be?

The most important part happens when choosing a build. This will determine how fun and interesting the game will be. I would recommend starting with something very familiar, even if you've only built such characters in trade leagues before (as long as they don't depend on unique items).
