Could offer whooooole fricken chunk of replies to this for myself annnnd the extended family.
Early Stormblood Rhalgr's Reach was absolute chore to sit through and evidently so fricken bad I suppressed it. Listened to much ranting from two friends who recently made it there, will never forget her quote; "I'm gonna punch this dumb kid" said to Alphy.
Every. Single. Time. the game forces you to interact with objects for needlessly long.
Quests that involve telewarping around all of Eorzea.
Anytime five quest npcs are standing in same room yet you must speak with each instead of doing so through one cutscene. Kinda stoopid..
Footprint hunting can go space its self, stop doing this.
The sheer number of quests that send you out into spot that is conveniently equidistant from every Aetheryte only to kill one or two simple enemies.
Everything involving the Crystal Braves. By the Twelve ARR needs some help. 90% of the quests could be deleted today and it would change very little about the story. Example; The escort the scientist for mister Bolder quest. No one so far has not become irate at this quest.
Job Quests and mediocre job stories that do not even act as tutorials for the job you are playing. Nothing interrupts the flow of adventuring like stop and do four job quests that no longer even give skills due to pruning.
Everything that has anything to do with Ala Mhigo. They are just umm.. just not that interesting. Every quest involving them bored me to tears and at the times caused feist. Will never ever forget a scene where the empire called them savages and they proceed to attempt stoning a child to death.
Countless pointless segways into sub-plots that have little to do with main plot. Seriously, these tangents go on so long that you occasionally forget which plot is even the main plot anymore.
As can play in Japanese or English (I have JP voices but English text so can see the difference for translation) the English. The verbose way everyone insists on speaking tries my patience. Talk talk talk blah blah blah some characters need fifteen paragraphs to say hello. Other times (accepting jobs anyone?) you are given long winded speech about entire history of something. Show do not tell works but all some do is tell. This is different in JP where character might only say "I disagree" while spewing forth two paragraphs in English.
Prompts defaulting to No then asking you yes or no multiple fricken times. Why the heck did the NPC just give me the entire history of the Arcanist guild then require I speak with them again so they could ask if I really really truly wish to join. Then speak with them again to obtain quest to speak with person six yalms away.
Areas broken up into multiple zones without reason. Go into the waking sands > now go into the solar > now leave the solar > now leave the waking sands. It is faster to telewarp to a friend!
Can absolutely understand why wiping in some easy dungeon after enduring two hours of tour de Eorzea might send someone into tilt city. Now if the content were more engaging.. which there is nothing stopping them from doing. Gunbreaker first quest? Sage final quest? Scholar quests? Summoner boss battles? They are plenty capable of not boring players.
