Are they going to adjust the Lamia Deathdancers in T7?

[Edli]

What I noticed is mobs have to attempt to attack whoever their highest enmity target is before a check happens to see who is the new current enmity target. What happens is deathdancer spawns usually with hate on a healer now then even if you hit them when they come out they will still want to go for a healer they won't want to change until they make it to the healer and see that the healer isn't the highest on the list anymore then go back to you.

Exactly, that is what I think happens. Is one of those quirks I got used to. I know the mob will come back to me so I'll keep doing my stuff but a new tank may get panicked and leave other mobs to pointlessly chase after something they have aggro anyway.

The same with lamias on t7, if you grabbed aggro don't bother chasing them, just go to whatever position you tank them on. They will not hit the player they were chasing.

I've stood right behind where they should spawn and hit them with a full combo'ed Butcher's Block, or really anything else usually besides an auto-attack as soon as they've spawned, and they still just take off for a healer or DPS immediately.

I see a lot of tanks try to engage these type of mobs with Butcher's Block or Rage of Halon. Try not to.
You may have top enmity, but the animation is so long for these abilities, that the "threat" level doesn't register, until the damage of the ability finally lands. Which usually happens AFTER the mob starts to move.
To avoid this, use Skull Sunder/Savage Blade or if you must (Typically with the third add) use Shield Lob/Tomahawk immediately after it spawns and run to your assigned spot to tank them. You can also use Overpower if you're doing it as WAR but just be sure that a Renauld has already spawned OR that it was recently dealt with, or you could potentially grab aggro from it and wipe your raid.
Skip to 1 minute in. This is the way I do it.

I personally don't feel this is a bug pertaining to this fight in particular, but a design flaw with the game architecture as a whole. Something that we brought to Square Enix attention during BETA quite frequently, but alas, was ultimately ignored.
The game has several check points server side, which can cause a second or two delay (Sometimes more depending on your connection). Throw in animation delay on top of it as noted above and you have a problem (This is why so many people have issues with Titan HM/EX).

You can work around it by pre-loading and basically learning patterns.
Unfortunately, if you have a high ping or poor connection, even that may not be enough and I suspect you may be experiencing a combination of all of these.

Which is why you pick up adds with loaded Savage/Skull instead of loaded Halone/Butcher.

^^ That's all you need to know. Don't use AE because you could get a Renauld in it. I would say that your success rate for picking up the adds without them moving is roughly 90% with Savage/Skull, they will still move once in a while depending on server checks but it is a very reliable method with low risk.

I don't even do that. I pre-ready a Steel Cyclone, pop it right as she spawns, then Tomahawk her until I get into place. I never lose the Lamia adds in T7. For the second, third, and fourth adds, I just Tomahawk spam them as I get into position. Usually 1 Tomahawk is enough to give full enmity on an add. If I get voice, I just use Flash on them, while facing the outside of the arena.

what Im wondering how will they adjust T7 so it can cater to people on DF once 2.4 is out. what if there's no smn or bard to kite renauds then its auto abandon already.

But Im sure they're gonna make major adjustments to it due to the nature of the fight. heck even groups that can one shot t9 always has issues with t7 each week, what more if its a DF formed group and a mix of JP and EN players.

It's true that it's not ideal to have anyone besides a BRD or SMN do it but... I've done it as MNK several times in some "Oh sh!t" moments with Howling Fist.
So I guess if you have someone smart/dedicated enough, it wouldn't matter.
Unfortunately, the chances of you getting someone that educated on the fight via Duty Finder are... slim.

Changes to T7:
Renaulds clubs have now been replaced with a pillow, the basic attack will now hit for 300 damage.

Possible they may force 8man DF to have 2 ranged / 2 melee. Or a healer can be expected to handle Renauds. Have done it in the past, just know for sure that many lazy healers will not like it if that becomes the norm.

As long as DPS isn't 4 MNKs, even a DRG can do Renauds with Piercing Talon.

The pillow damage applies Echo.

If you hit them with BB, it's the 3rd swing of BB that will fully register the enmity which can take forever. You'd still should get it though. It can run off to the middle, but it will come back hitting no one.

Just throw a tomahawk, weave in bloodbath or something else and start your rotation if you want to be be absolutely sure.

I agree that the way aggro works can be tricky. I don't think it needs to be fixed since it doesn't seem broken for t7.
