I did Titan before getting a static. I'm not the best but after doing it repeatedly I wouldn't get hit by anything.
Titan is all about memorization and muscle memory. Not the best design, but I don't mind it once in a while.

My connection isn't very reliable either. When it's good, you can dance in the plumes for a while before running out.
When it's not, a millisecond more reaction time would mean getting hit. Still, you can compensate for that, it's just a pain.

I'm not going to applaud Titan's fight design. I think dodging the floor and linear one shot mechanics are cheap.
That's not to say I don't enjoy the fight. I do it for fun all the time. I join people in PF just to help them out.
If all the fights are like that, I wouldn't like it. Thankfully they're not. People just make a big deal of it cause they get stuck there.

However, there's a lot to be said for the sense of accomplishments walls like Titan bring to end-game.
It could be better done as a fight, but the function is the same.
Like I said, I did Titan before being in a static and it was tough. When I got it down, it felt great. I felt a sense of accomplishment.
When helping people do it, they're always so ecstatic if it's their first kill. It's even moreso if they use VOIP.
I think that's a great part of playing an MMO, and honestly not many fights give that sense.

So I think Titan is pretty has a pretty good place.
