If I see anyone in-game demanding others to read up strategies in the first month of Heavensward, I'm going to /slap them.

Also:
  • Make space in your retainers. You will accumulate new items and materials during your adventure and you will not know what to do with them. With the desire to push ahead to level 60, you will need that storage space for those drops to either sell later or use to level your own crafting.
  • Some of the Level 50 dungeons will not give EXP. This is because many people will find it easier to speed run Lv 50 dungeons for EXP than to run new dungeons. So it was revealed in an interview at when 3.0 is released, at first these originally end-game Lv 50 dungeons will not give EXP.
  • Don't neglect the daily roulette bonuses. Combined with rested bonus, the daily low-level roulette was one of the key tools for me getting all jobs to 50. We don't know yet exactly what will happen to the roulettes, but it is something you should check out and use to your advantage if possible.
  • Don't neglect the weekly challenge log. Each item is either 5% or 10% EXP of your level.
  • Stock up on cheap vendor food. Even if it's only 3% EXP bonus, it adds up, especially for those who are going to do dungeon crawl where the vast majority of your EXP are eligible for the bonus.
