Was thinking of this post. Prior to this statement from Jascha, it was found out that it was automatically activated once you hit 150. Never looked into it again because we didn’t want to hit that much RP in 5.0 because it would have taxed our donor planet into oblivion lol. So apologies for the out of date information, was already addressed, apparently.
As for RP amounts, I would not suggest more boosts for Trader, atleast without it matching the playstyle. Honestly ever since RP was tweaked to require Warping in 4.0, my interest in RP has only been in having greater than 1, so that faction supply was accessible. But I do see and like the new RP oriented additions, should bring significance to RP, which is excellent.
