Yes, I read it, twice now.
Plunder collected is rep. Rep is gained from collecting Plunder.
From the article:
“pirating players can double the amount of Renown earned from all sources of Plunder by taking the Plundersurge”
So, unless they cap your plunder gains at Renown 40, this will make the 1 mill FOS easier. No idea what you meant by “fairer”. I don’t see them doing this though because of that FOS.
So you’ll collect plunder now at double the rate, from all sources and if getting to 1 million is your goal, now is the time to do it.
I can see now how you are reading it.
