You seem more intent on having SE nerf the encounter, instead of learning the fight yourself. You said you tried a total of 3 times, and stopped because you didn't beat it. That's just plain silly. Do you really think these raid encounters were meant to be learned and killed within 3 tries?

Even Collision doesn't beat fights, that they're new to, in 3 tries. Put forth the time and effort to get your kill, or stop bothering with it. T5 is far from difficult. It's entry-level now, thanks to echo. If you can't get T5 down due to lack of patience, there's no way you'll stand a chance in SCoB.
