TL;DR at the bottom
Some achievements as they are right now, are a grind. Some are meant to be a grind and that’s okay, I’ll get into that later. If we take a look at Southsun Survivals achievements you can see that if somebody wants those achievements they have to do the exact same task over and over. This is an example of a grind that is not okay. My suggestion would be to lower the amount of times a player has to do the task in order to get the achievement, make it as low as doing the task one time and no more than three times. After players finish the original tier(s) of the achievements, you can give guaranteed rewards to players who finish an extra bonus tier of the achievement. You guys already have the Loot Bag rewards but I suggest you expand on it. The bonus tier can be an extra incentive to keep doing the task for players who really enjoy the content. The reward for the bonus tier can be something like the new Desert Rose backpiece item. After players finish the first achievement (worth X amount of achievement points) they can continue to do the content for their extra reward which includes zero achievement points but the guaranteed bonus item. This way players who want the achievements but not necessarily want to do the content over and over can complete the achievements with little complaint, and the players who enjoy the content can keep doing it knowing they will eventually get a reward for doing it enough. I also suggest these bonus item(s) can be available for sale on the Trading Post for the players who want the items but do not enjoy the content, and for the players who enjoy the content but not the item, which they can then sell it on the Trading Post for gold.
Now, I understand there are some achievements in the game such as the Slayer achievements that can understandably be taken as a “grind”, although eventually with enough regular playtime you would probably complete a handful of them without even noticing. Achievements like these, in my opinion, are okay to be considered a grind. The reason I believe those achievements are okay to be grindy is because like I said previously, you will most likely finish a bunch of them just by playing, and if you so wish to finish them all ahead of time you can go ahead and grind them out.
Another example of “grindy” achievements that are not okay, let alone humanly possible to finish are the WvW achievements but I understand you guys are already working on fixing those achievements so thanks for that.
These are just suggestions in the end, but I do feel strongly about getting the achievement system set in order.
TL;DR
Some content is too much of a grind coinciding with achievement rewards to be enjoyable. I suggest reducing the amount of ‘grind’ needed to earn the achievement points and instead give a non-achievement point bonus item to players who enjoy the content and play it regularly.
