Turn 5 Aggro bug, dragoon consistently being targeted on pull

Date & Time: Mar 13 & 14th, 9am to 11am JST; multiple times in past runs, including pre-2.16, pre-2.15

Frequency: (2) Sometimes - it seems completely random, we can't nail down a trigger for it. On the 13th it happened every pull. On the 14th, it only happened 3 times.

Character name: Arche Koeln

World: Sargatanas, but inside the Binding Coil of Bahamut turn 5

Solo or Party: Party with Xiomane Snow, Melila Rixyuu, Cowgomoo Rixyuu (dragoon being targeted), Omnom Nomnom (14th subbing in for Evileye), Evileye Lakshmi (13th, usual member), Ty'fun Paradis, Tycho Taru, Caladius Numara

Monster Name: Twintania + Scourges

Steps to Recreate:
- Tank pulls Scourges via shield lob or proximity body aggro
- Everything rushes for the dragoon, or it doesn't.

I have no idea. I can say what we've tried to rule it out, but it seems completely random. We've tried multiple approaches with different methods, but it seems to trigger regardless of what we do, with no consistency in when it occurs, only that it targets our dragoon every time.

Ruled out:
- Alphabetical Aggro order. His initials are C.R. Neither forename nor surname are at the front/back of the list respectively. We have A.K. (me), and X.S., neither of whom take aggro like this.
- Buffs generating enmity. He doesn't precast anything. He just sits there.
- Proximity. They've targeted him even when he's been outside of the lockout zone line.
- Occurs when tank body pulls.
- Occurs when tank skill pulls. (happens both ways without consistency)
- Lalafell only - he's not a lala
- Doesn't occur when tank pops a cd to generate buff enmity after initial pull - still occurs.

I did find several threads discussing this, however no bug reports turned up on search.

I recorded a few encounters of this as well.

0:00 - Tank initiates, drg pulls aggro by existing, I pull aggro from a poorly-timed adlo.

0:11 - Tank initiates, but body pulls before shield lob hits add, drg pulls aggro by existing

0:17 - Tank initiates with shield lob, drg pulls aggro by existing, blm pulls aggro from the lobbed mob.

in your video C.R used something on the pull just before tank go inside on first try. same thing for others
nobody except tank must use a buff at start to have an aggro by buff on pull. your tank must go in middle of pack (to body pull too) not by side and cast a buff just on the pull (it s the cast of buff who generate aggro not the buff himself).on each try of your video tank cast buff before pull.
you just have to work your start. everyone had the same pb until finding the best start :D

Does he draw his weapon manually before/at the pull? I know this seems like a silly thing, but you seem to have ruled out everything else I can think of.

i was gonna say the same, i keep face pulling on my bard in dungeons buy doing this ^^

Our bard always has initial threat during the pull as well, even if he's way in the back. We started using this to our advantage and have him facedive with the tanks so they can just pull off him.
