Fights will inherenty get nerfed from increase iLv, why do we need echo as well?

[Versiroth]

If a fair amount of players can clear for instance T5 at i90, with an increase of iLv and gear, the fights will naturally become easier to complete; the echo buff seems hugely nonsensical in my honest opinion. Does anyone think echo is actually a good thing to implement?

BC 1-5 will be primarily for people in ilvl 70 to 80 gear to hit ilvl 90. The echo buff is for those groups so random pugs can handle it. If you're already ilvl 90, you should be doing 6-9.
