Most Annoying Quest/Mission?

Yup all those useless fetch quest that doesnt come with a map marker, which started in EOS, they are annoying but could still find them and complete the quest(think except for the scanning of colonist bodies one...  is it bugged?  I could never complete it.)  When it reached Havarl with the rokkar manifestos and the one that some sage gave towards the end of Havarl, I really couldnt bother,...  After that was Eladdin with that dumb little mouse...  Also the quest that doesnt show up on the journal, eg the sick dude in kedara together with the salarian with the light bulbs.  Found the 2 druggies, found the "medicinal herb" but couldnt deliver it.

Also after my 3rd playthrough and now on my 4th, I decided not to do any quest(except the main ones) that the outcome turns out negative.  Eg the angara at aya who gave me a quest to fly around looking for his satellites, in the end found out that it was some kedara outlaws that stole them and he's blaming all milky way folks for it.  Bloody ingrate.

I plain hate those missions copypasted from DA:I (randomly appearing slaves, books, etc). Didn't anyone tell Bioware back then the design of these stinks? Honestly, I never replayed DA:I just because the unbearable respawns and level of grinding needed to complete these.

Anyway, in case anyone from Bioware will ever read this, please, pretty please, never ever make quests like these again, even if you're making a game for your worst enemy.

These quests are so horrible they ruin the overall game quality and feel like a meaningless filler artificially prolonging gaming time just because.

Here's the list of those in case someone is not sure which design I'm talking about.

Eos:

- Data Trail

- The Ghost of Promise

- Watchers

Voeld:

- Catch and Release

- Clearing the Air

- Gone Dark

- Subjugation

Eladeen:

- Cache Flow

- Infection

- Little Mouse

- Volatile

Someone mentioned Naming the Dead, but that one, including Roekar Manifestos and Local Cuisine have objectives at fixed spots where unnecessary grinding is not required, thus were not annoying to me at all. I do like exploring. Backtracking just because something might have appeared somewhere I visited already, but it's luck based, I'll never like.
