Uploading a video as you decribed prooves nothing. Latency works in all mmo's like that. Having someone follow me isn't going to appear that they lag behind, e.g. I move 10 feet before they start following me, that happens in WOW too. That's because of the latency between me moving to the server and to them and them moving to the server and to me. That won't demonstrate anything if I frapsed it. That's internet latency 101. Data does not transmit instantly and that's not the games fault.
What I should do is get the same 7 guys I ran titan with last night and record our fight where we had Zero deaths till phase 5, and every death in phase 5 was from Bad Spread on the 6 plumes that come out (positionioning) I should upload 2 videos, 1 of the fight with me narrating it, and 1 with the fight with team speak chat. Not hearing that team speak chat is missing out.
The entire encounter I was calling out every single ability as it was incoming
P1: Landsldie incoming... Ok stomp next
Geocrash stack on tank
P2: Plumes coming spread out from each other as best as possible (cool no one hit), Landslide incoming, Stomp incoming, be ready for plumes next
Geocrash stack on tank
P3: etcetc
p5: Now my tone as increased and I say "Top oFF tank incooming MB, Now medica that stomp, now Run and spread OUT like MAd Shit tons of PLUMES INCOMING"
Me calling it out is what made it really easy.
The main problem with titan HM and BCB is communication. And it's rooted from this,
Square made 1-49 SOOOO EASY, that people go into titan for the first time expecting to face roll it like everything else. Having a fight with complex mechanics where they need, GASP, "Communication", just blows their mind. WHy oh why do we need to do that here when we didn't anywhere else, is something like what they say in the fight.
I can tell you I've raided in Many MMO's, From FFXI, to Vanguard, WOW, and now FFXIV, and I've never been in a raid where we weren't in a voice chat program (like ventrilo) with a raid leader. Our titan run yesterday I was the raid leader, and we 2 shot it.
I can also tell you that there were many mechanics in wow raids that were lag/latency/luck reliant. You would hit it or you'd get screwed from latency or a lag spike, just like Titan HM. Sindragosa's Ice Prison's in heroic mode come immediately to mind, and Grobulose's poison trail comes to mind.
