Any HM class or higher trial has Echo on it dude. I even think Dorm Chimera and Hydra have it now. You have to survive for at least 5 minutes in the trial With Out Dieing before it'll activate though and will go to a maximum of a 20% boost to all stats.

All levels of The Binding Coil have echo activated from the start. From the first turn of the first coil all the way to the final turn of the final coil, you get the 20% buff as soon as the raid starts. (You don't get it in any of the Crystal Tower raids btw)

So what are you wiping so fast that you're never seeing echo? More Data needed man.
