T6/T7 AAT difficulty comparison

On normal p2 you can find droid teams doing like 4m damage, in the heroic mode this same team will do 1.5kk

Thanks.Can i assume this is 1:2 ratio between heroic/T6? Any other examples pls - for instance in P1?

Comparing direct damage values between T6 and Heroic is pointless due to the vastly higher health pool of T6. Better to compare the % damage done to each tier and phase.

sure dude. My goal is only one - to see if my respective squads are ready for T7, and if not, when they will be.

The main difficulty of heroic is that you can only use each hero once thus you really need to optimize usage of your roster. Each phase requires having the right team composition and that applies to the whole guild (or most part of it).
Other than that the raid is not so difficult as people think - it basically requires 20 heroes, and most of them are or was meta so if someone cant build 3 raid teams he either started to play too late or he is doing something wrong.
