Fishing requires much time and does not yield much profit until its later levels. Unless you enjoy it for its own sake, avoid seriously delving into fishing until your level limit. It is not a bad idea to do a little when starting out a new character on a new server, though - the gray items you fish up sell for good money to a starter, which can help you out with your other tradeskills.
Play on autopilot and stop thinking about what to do next. Instead, i suggest you look at the best alternatives. Thank you dugi you are the undisputed best. You may have to repeat some of the dungeons to gain enough xp to level up, but you can help out someone else at the same time. You can find out what professions make the most money, which ones can benefit your specific class, where certain items tend to appear for harvesting/mining and a lot more.
This section will be a brief section to look at the talent advisors in both Dugi’s guide & Zygor’s guide. For new players having a talent advisor is a perfect feature, as you probably don not really know what talents are good and what talents are not. Even for us experienced players; rolling an alt might be difficult at first as we have to research good talent builds for leveling.
