No it doesn't (just to the travel infrastructure.) In fact it is likely to alleviate stress, as more RAIDING will be happening on Chaos.
What I mean is when you apply to PF, you are immediately logged of, and your travel starts. Only when you get there can you chat to the PF owner. If the PF isn't starting for 50minutes and you have to farm FATEs too bad. If you find out they are only playing for 15minutes... and have to leave the PF... too bad. Again, its better than what we have, some will still perma transfer, but some won't and that's all that matters.
See above.
I 'm not getting the point here or problem I'm afraid. I'll only say travel already works. Those problems have already been solved. (saving for at increased bandwidth/increased travel)
In a word yes. An application to a PF place on another DC is 100% equivalent to being at the XIV client lobby login in screen > selecting 'travel to Alpha:Light' > 'are you sure' > and answering 'yes' and 'login' all in one go.
But you 'can' cancel during that travel process as you can now. And that will just signal the PF to release your place.(see below also)
Not unless the coders are incompetent and have never heard of 'TIMEOUTS'
If you apply to a place, your going to take it when you get there. You could sabotage PFs by wasting peoples time no matter where you are. You can do that now. If after character travel, your character then never appears in that server's login queue... (becuase you've DCd) the PF place is released.
See above. Its just all of what happens now. IT is just a question of signalling, and timeouts, to update that PF place reservation.
I see no reason why the current error handling experience can't mostly be preserved. But where it can't be, then yes, this will be a disadvantage of travelling, but again, its better than what we have and thats all that matters. (much better)
As for the blacklisting yes that's not ideal... but
(a) its better than we have
(b) I'd suggest you can prevent people being able to kick until the person arrives.. (at which point only a vindictive loon would still do that because they've already had to wait and the wait is now over) You can even lock PF disband until the transfer is complete if you wanted.
(b) and what are they going to do, block every player on Chaos. It not going to help until after that person has turned up. It won't help much in the future as they are unlikely to see that smae character again (at lest soon) but 'will' be seeing another Chaos player (and they will start to see lots... its going to piss other players in their PF)... in short its not giogn to work for them to their advantage. And they will work that out eventually, or only they will suffer ultimate anyway... so let them.
If Light community went crazy and started boycotting Chaos users en mass, that is something they are goign to have to proscribe in general T's&C's behaviour, and the GM's are goign to have to start saying "'why' did you kick them? I'm not seeing anything in the game chat logs. That's the 21st kick you've done this week that we've had a complaint about, with no contact with the player in question, we can see they are all Chaos players. Stop now or the next time we speak enjoy your weeks Ban. This is our game there are conditions you've agreed to, we don't have to give you the benefit of the doubt, play nicely or don't pay and don't play."
"A: oh,, we kicked them for their FF logs"
"Yeah? well again your banned."
