Is it best to interrupt Mind Flay as soon as one of them procs? Should I wait for the last tick before casting them? Or should I be using some kind of mod to interrupt it in the middle but immediately after a tick?
I've heard conflicting reports about the accuracy of mods that try to display MF tick points on the channeling bar, so I've been interrupting immediately for MB but waiting until the last tick before using FDCL procs.
