There is currently a system in which you need to accumulate 100 points to gain access to missions on Auric difficulty. You get +10 points for a win on Damnation difficulty and –5 points for a loss. However, many players complain that this is too weak of a filter, and it’s easily bypassed by people who shouldn’t be on Auric difficulty at all.
I believe this filter can be effectively strengthened: +10 points only for completing a Damnation High Intensity mission, and –5 points both for a loss and for leaving the match for any reason (0 points if the match ends in a successful extraction but the player themselves fails to extract). Only matches played by the player from the very beginning should be counted.
I fully admit that such a filter would effectively lock me out of auric-tier missions as well—except when I’m playing Ogryn. In my last 11 attempts to beat Damnation High Intensity as Psyker (3 runs), Zealot (2 runs), and Lone Wolf Arbitrator (6 runs), only two of my runs were successful (both on Lone Wolf Arbitrator).
The exact same approach should then be applied to Auric HISTG missions. Only after accumulating 100 points on that specific difficulty should a player gain access to Auric Maelstrom, and only after accumulating 100 points on Auric Maelstrom should they gain access to Havoc.
And of course, each class must climb this ladder separately, and the Havoc rank must also be earned individually for every class.
