Forces not strongly hit or helped: Guard, Dark Angels, Codex marines, Orks, CSM, Damons, Nids
Forces simply helped by weaker psykers: Necrons, D.E, Sisters, Tau, Templars.
That would leave Guard and DE at the top, shove the marines +1 down, and help many of the weakest armies into mid-tier.
It's about as likely as Tau sweeping every tournament this year, though.
* short of reviving some stupid 3rd/4th ed rules, like assault from close transports, consolidation into combat, that kind thing
