With the advent of Stormblood, my friends and I have been discussing the newbie experience. There are attempts to try to help newbies, but they don't streamline the number of quests and levels required to reach other players.
Suggestion number 1: Make the newbie ring give bonus xp up to lvl 50.
Suggestion number 2: Make LEVELING ROULETTE ACTUALLY LEVEL YOU! Just make it auto level you by one, or better yet just make any dungeon within 4-5 levels of your current level auto level you
Suggestion number 3: With the scrapping of classes, make unlocking ARR jobs start you at level 30 like it does for heavensward.
Suggestion number 4: Make a potion that allows you to skip the ARR story. This needs streamlining, there are way too many quests to get through and so much effort needed to catch up to anyone who has been in the game for a long time.
Suggestion number 5: Make a potion that allows you to auto level 1 job to lvl 50.
