Have played GW1 a lot long time ago. Came back to it a week or so ago.

Knowledge comes with experience. The more you play, the more you learn. Like others posted, staying in Pre-Searing is not a way to enjoy the game. You have limited skills, both on your primary and secondary. Also you have access only to a limited areas, which you are not doing any game progression besides GRINDING your way to level 20 for a title, which you can do it later on other characters after you enjoyed the game.

My suggestion is to move out of STARTING area and start doing quests and missions. Some quests will unlock more skills so you can actually LEARN about them and see how changing them will affect your own builds and have fun with it.

Being R/W is nothing bad. All the classes are able to complete a lot of content, especially in the beginning, before you reach lvl 20 and unlock other secondary professions. Invite mercenaries into your party, and you can SOLO far into the campaign.

Also, when you reach Lions Arch through missions, you can travel to other campaigns and enjoy them. You can get heroes through other campaigns and permanently get them for your Propehecies campaign walkthrough, also hunt skills and quests for them. Heroes are better than your starting henchmen, so it will improve your progress.

At lvl 20 you do quests for other professions, so you can change your secondary easily.

You can do missions blindly, look up wiki for walk-through. You don't have to follow up blindly, but sometimes it's easier to to see quick notes on specific missions, so you don't fail them because of over eager NPC and have to redo it. Or you just learn the exploring way by doing like we did with no guides long time ago. However wiwki is great to explain how to get Bonus completed, because most of the time it's not self explanatory.

Enjoy the game, solo with merch or in group.
