For Q1: I think we should probably archive them because the new system has buffed the player alot I feel like and there has been many improvements. Also now with the new Etching system it allows for some nice buffs straight out the gate kinda thing which does change the nature of the runs.

For Q2: For the Ren levels I would say either adding level 6 or 7 depening on how players feel about the challange but personally I would say just add Ren level 7 to Any% and Co Op because it just fits as its the new highest difficulty. I would also say Leave Ren out of Foundry only because that is just never ganna happen that ppl run that unless they are crazy.
