Hi Welcome Back. I was in a similar situation few months back when I returned after a long hiatus. I would highly recommend starting a new character and playing it to the point where you are familiar with the game's mechanics. I chose Ranger as my new character, but the other noob friendly professions are Necromancer, Warrior and Guardian. As you might know the game is divided into the core Tryia regions (where you level from 1-80) and then maps that are part of the expansions which are all level 80 (heart of thorns, and path of fire). The expansion maps are significantly more difficult and definitely not ideal for new/returning players. The mount quest you are doing is part of the expansion map. However the mount quest itself is not too difficult.So i would recommend starting a new character and leveling it to 25, then go back and finish the mount quest using your ranger (this unlocks the mount for all your characters). It will significantly help how quickly your character moves across the map which helps leveling speed. Then you can go back and continue working on your new character to a point where you are ready to try your ranger again. And to get comfortable with the ranger i would recommend doing some quests in the level 30-75 zones of the core tyria map. That way you can familiarize yourself with ranger's mechanics without having to worry too much about survival.Quick note: Elementalists are one of the hardest to play. They have poor survivability and require a lot of skills to be spammed in short amount of time. However they are fun and do insane damage.
