Thread TLDR, based on responsense..,:
You lead by example, if you ain't comfortable, say so..,
I'd assume a Number of the DPS that run ahead, or healers(co-tank in some rare duty) tend to stop before enmity range. [Depending on how much they've done the content, they'd have learned the range limit, or do a Lil accident]
Pulls/Attacks/Heals while the party is moving doesn't really hurt anyone, long as they group them up on/within range of the tank.
<when BLMing, I tend to go a bit farther/ahead than the tank when we reached the wall, so that I'm away from the AOE, but we'll withing their smacking range. if anything did get ripped from them, then the mobs wouldn't be behind them, but right on them. same with other dps, but that's just me. as I have decent enough experience on all the roles. Heck, you'd aoe Medica 2 in the old Castrum to pull the adds to you, for easier aoeing the adds>
The trolls are apparent, some may even play reasonable, till you call them out on some hypocrisy.
<got that from a lala that claimed I ran ahead as healer. (was waiting well out of Enmity range) only for them to do so later. Called out, they started trolling, getting the tank, and themselves killed constantly. Thus me and the Other DPS had to Duo the boss, unfortunately they pulled the tank down with them.>
A good Party knows well how to work together. Of course there are many new players, as there are old, or rusty ones.
So it tends to lead what your own assumptions and expectations make you react.<I know for sure I, and many others I interact with, would have some cooperation/expectations if competence, but understand that there are just days when one isn't doing so well..,>
We all want some rush going through us, if we die, we die. if we KO, we KO. if we Succeed, then all great.
Sprint as far as you can handle. if you aren't sure, let others know..,
If they are a ______ or a troll, it'll be all too obvious, they like being caught.
But most bad situations tend to be unintentional for sure.., and have the most basic or simple explanations.
<like gear, I feel oh so surprised when I rip off a tank, but I understand, I just go with the struggles.>
edit:
My Personal TLDR:
Usually best for the party to be stuck on the "Tanks Rear Defense", be they sprinting, or running.
It's what I'd do regardless, of they DC, or afk, well wait ahead til they get back. or slow go it.
If they're failing it, or clearly stalling, that's on them. Other wise, as Jocat says.., I'll stick to the tank, like a _______
