I love the game, but... Titan

[Kirhs]

while i totally agree that every mage should have swiftcast, as it is an invaluable ability, its not going to make the difference in a win or loss vs. titan in this instance. If people in your party are continually eating plumes to the point that you need swiftcast to counter their HP loss, your party is not going to beat titan.

Swiftcast generally won't be used on plumes. Most likely if someone is hit on p5 its a one shot. What it is exceptional for is getting an emergency heal off during stomps p5 so you don't fall behind before plumes fire off. Especially if the tank takes a big mountain buster hit or you're a bit late on a cast. It smooths over a rotation.
