What things annoy you?

[Shurrikhan]

• Mob return distance is based on their distance from the center of their domain, rather than their distance from you. This is especially annoying when their domain center is at the edge of a FATE or even beyond that, such that they're resetting from being dragged even to the middle of the FATE now that the return distance has been shortened. It also means that it can be nearly impossible to deaggro something that's now attacking someone or something else which is not fleeing from its domain center.
• "Unable to execute command while occupied." I can understand it some cases, but I've never seen a more UI-restricted game.
• Loot roll check procedure. If someone rolls Need and no one else even can roll need, they should get the item, rather than having to wait until the afker returns to roll.
• Server tick skills, be it Meditate, Anatman, or old Umbral Ice. First tick should be instant, then at a % of GCD.
• Leaving the MP gauge tied beside the HP gauge despite half of all jobs not using MP at all. (And half of those who do use it merely keeping it a gauge to excuse bloat via LD and/or a permanent rez tax.)
• Macros being purposely handicapped via lack of queue function to ensure players can't circumvent button bloat even if they so desire. We should either (my preference) have gameplay that cannot thus be reduced to a rigid sequence without losing performance or (lesser of evils) be free to combine those rigid sequences as we like.

Edit: Whoops, misread the OP. From players specifically...

• Incompetence resulting from active negligence.
• "Prince/Princess healers".
• Tanks who hold their parties hostage.
• "You don't pay my sub" (but I can force my preferences onto 3-7 others with impunity) players.
• *Counts down from 20 despite only having a Monk to possibly wait on and that the Monk is already in Coeurl stance. Pulls at 7 (when said Monk has been forced back to Opo-opo or Raptor).*

Waaay too many confirmation windows
sometimes even confirmation window of confirmation window

Blame Microsoft Windows double check school (Search the reply from GM to Microsoft critics about automobile)

For dungeon bosses I agree. It is not needed. For trials and normal raids though it never hurts to check to see who is or isn't afk before it begins.

• The RNG factor in crafting. Shit's already hard enough to get crafted, really don't need RNGesus to help me fail at them
• The housing situation on pretty much every server
• People that feel the need to comment because you're not adhering to their standard
• Inventory management
• The interface : everything needs to be done in specific steps, e.g can't perform an action while in crafting mode etc.

This for all eternity. There's a reason why crafting feels so high stress, and the RNG is the culprit. It's also why I really dislike regular fishing, there's not many ways you can manipulate things into your favor.

• Tank that are impatience, have to pull the boss even someone miles away
  Tank start blaming other when a wipe happen
  Healer that forget their primary job
  Healer that forget they have Esuna
  Anyone that think healer will pull their HP up so they could comfortable sit in avoidable AOE
  DPS that are so impatience have to pull next pack of mob or boss without first talking to the group
  Rage quitter who quit after just 1 wipe
  quitter who quit before the run even start
  Fail my touch even it is 90% success
  Fail my touch twice in a row even it is 90% success
  Fail my touch 3 times in a row even it is 90% success

That so much of the jobs and the changes to skills appear to be based on the raid players and content, when there is a large portion of the population who play this game more casually, enjoying dungeons, and other content. Seeing jobs get gutted, left out of content, played less because now people who do raids have decided that the job is not effective enough is super frustrating. The fact that Social Media players who have a large following can have a significant level of influence on jobs that they admittedly barely play while the players who main those jobs disagree with the changes but are not heard. Why focus on only one area of content when you have a huge game that offers multiple opportunities for play? Isn't that supposed to be one of the great things about FFXIV? I have played and enjoyed raid content, but I also enjoy other areas of the game, and I have many friends who do not do that content at all. I also see the focus of discussions becoming about how individuals need to play their job most effectively...Isn't part of the point of an MMO and the challenge that you cannot control everything because you are playing with other individuals? If I wanted to control everything and not have to deal with other players, their style, or enjoyment of the game, I would NOT be playing a multiplayer game. As much as I may get frustrated, I also enjoy the challenges of group dynamics and having to adjust to the level and quality of the individuals I am playing with, it is part of what challenges the game.

As much as I see people saying this, it's really only an issue if you're trying to craft items with absolute bare minimum required.

If properly geared not even the latest ShB crafts have a meaningful amount of RNG involved with them aside from getting a Reuse proc.

I see your ready check and add an 18 second timer before pull after it
