Echo in Raids

[VerdeLuck]

Echo only really helps with passing damage checks, the big killers in most raids are mechanics. A damage bonus won't help when the Refurbisher absorbs too many adds and explodes because nobody was handling the generators.

Echo helps with more than just DPS, it increases HP, Heal Strength, and Shield Strength. The ability to survive more than 1-2 failed mechanics definitely helps new people get through the duty.
Honestly if a party wipes enough to build up an echo in normal mode just let them have it.
