You wouldn't believe how many times I have to use provoke when derp DPS hit the wrong mobs or a whm goes medica 2 happy right off the bat.
Flash is less powerful, but has advantages:
-it saves your tp bigtime
-casting time is faster
-it's 360 degrees so it's great when mobs are scattered
-you can use it during pacification
-oh and it won't break cc
