Love:

1. No subscription fee. No down-times.
2. The free-to-play model, and how accessible the game is in general.
3. Action Camera and all the other camera changes we got in the last year.
4. Expensive or hard to get gear won't get obsolete with time. All future added content will most likely stay relevant without level-cap increases.
5. That Anet is actually trying to fix the game right now and even rework "old content" (Shatterer, Cliffside Fractal, PvP maps, ...)
   I hope they continue this philosophy with the old Dungeons or the Core Tyria story. That stuff still needs fixing too Anet! please.

Hate:

1. that I can't play or experience 1/4 of the story anymore (Season 1). I hope Anet still considers working on it.
   Even if they make most of it instanced or retell the story in a different way (like Queens Jubilee can be a story instance similar to Party Politics from Season 2, where we talk to the guests, Queen Jennah makes her speech, and then Scarlet shows up and ruins the party. But have Queen's Jubilee and the Queen's Gauntlet as it was as a festival once a year but without Scarlet interfering, ... ).
   Things like the Tower of Nightmares, Molten Furnace, or the last fight with Scarlet could become dungeon paths (for 5 men or soloable like Arah),
   The Marionette a World Boss (there are several maps in GW2 that are stuck in time so why not have that part of Lornar's Pass be before the events of Scarlet's defeat?),
   and the Attack on Lion's Arch and Southsun Cove a farmable meta event map you can go to whenever you like. That restart every 1 or 2 hours. And last but not least put old Lion's Arch back into the game. Let us choose in which City we prefer to load into.
2. that Season 2 wasn't bundled with Heart of Thorns. Isn't it crucial to the story of HoT? I hope everyone that bought HoT will get Season 3 no matter what ...
3. That lower tier leather and are not obtainable though salvaging level 80 gear. I would like that system to be reworked somehow.
   I probably have more points but those three are the ones I'm most passionate about.

Still enjoying the game very much! o/
