Remember though that the power of naked DoTs vs. the power of MG was changed up not because of DoT snapshotting but because KJC was going away and it was a hot mess in PvP.
I agree that removing DoT snapshotting will allow devs to place more of an emphasis on rotational mechanics. Just don't forget the PvP problem with such an emphasis on MG.
Devs always had a hard time balancing Aff regarding multi DoT fights and single target. Pandemic and SB:SS just make it more pronounced.
