Yareli Prime (my oshi frame) was released in Warframe today, alongside a pretty expensive pack with exclusive cosmetics. You can still get the frame for free by farming it, the only thing you need to pay for are the cosmetics.

Damn, I'm glad I play a completely f2p game that has no p2w or gacha elements whatsoever so I never fall into any trap of paying more than I would pay for a AAA game just to have a cosmetics pack...
