Titan issues that need addressing.

This right here. You don't need to watch the castbar at all, everything is perfectly dodgable by just looking at the telegraphs.

..UNLESS people are either slightly slower than you or working with a slightly slower connection, in which case not having the first third of the castbar going to waste could certainly be helpful.

I mean, I have to believe that if the designers decided that the cast time on these abilities should be X seconds long then the idea is for players to have all X seconds available to them for movement, not "whatever Elazu can work with". Kind of a safe bet, no?

Edit: By the way, the person you're quoting/agreeing with is trying to make the point that the castbar is critical, where as you seem to be implying it can pretty much be ignored (as if the information it provides isn't crucial for a successful dodge).
