Why would a Hard Mode primal drop an i95 weapon when the current extremes drop i90? That would mean that leviathan hard mode, a story mission, would be as hard as t5 or at the very least be harder than the current extremes.
The Rowena tokens seem to have switched source.

It now says for the delivery of beastmen tools.

So I think the extreme primals keep their accessories, and get that new mount drop for each, while Leviathan EX gets i100 weapon. But that the Rowena token thing is no longer from doing the trio of extremes.
