Long time lurker, first time poster
I can confirm this behaviour, tho I don't think I have the screenshots still. Basically, I discovered this same thing when after blowing TP + Wing on my THF/NIN I went up to keep an eye out for Y&Y while the rest of my LS continued killing DL at the usual place(i.e BLMs & mages on the top of the cliff, DL and melee on the bottom).Have someone stand in front of Zvhal before they are summoned & fight DL at the bottom of the bridge leading up to Zvhal. When he summons Y/Y they will aggro the sacrificial lamb on the way & then reset because their hate is not yet linked with DL. I am not 100% sure if this works, or of the distance DL needs to be away for it to work.
I was basically sitting right in the middle where the path narrows towards the gates when Y&Y popped and proceeded to aggro me.(Note: I did not range attack or otherwise claim them) I tanked w/ shadows for awhile, then popped PD which bought about 1 min or so of time before they eventually killed me... But, instead of continuing on to ravage BLMs, they resetted long enough for me to reraise and sit on the path again (About 30 seconds, before they started moving forward to help DL again). They reaggroed me and I died again lol, BUT they resetted once again for another 20-30 seconds.
Don't know how much this would help tho cos if you've been in a successful DL kill, as you know, if you've been fighting DL for nearly 3 mins, shit is going wrong already. >_>;
Theory is, if you aggro the dragons before they can spot or get close to the alliance they will reset temporarily but eventually they will rape you horrendously.
In my dyna shell, we usually pull off 2-3 THFs who've blown their tp to go distract the dragons by using this method and it has worked so far almost 100%. Its been awhile tho since we had the numbers to kill DL again after getting 7 kills.
