Without free plat and those 10 plat cryo gear crates I would have quit midway to 56.
This is compounded at end game. Wanna farm? Need good gear, how to get besides km3? Farm elites, what's needed to farm elites? Lots of great gear that doesn't drop. So back to the slave mines.
Wanna farm that nekro- you need enough high level gear that if you had it, you wouldent have to have nekro.
If you are not rich endgame is entirely content related barriers.
