So @[DE]Drew these Arbitration changes
Arbitration made as hard as existing modes but still on a reduced reward rate?
New Rivens locked behind Arbitration Mode
In addition a new, horrifically expensive resource to grind in order to remove a limitation on our warframes, involving a resource that will require us to grind modes away from the Arbitration mode (Forma from Voids and Nitain from Wolf)
Revival mechanic in arbitration that further punishes the remaining team members beyond being a player down
on the other hand
Arbitration is still just a recycle of other modes adding nothing interesting game play wise to keep players interested in the game
Arbitration Drones still make none damage tank builds pointless negating 75% of "how to play" a player learns unlocking the star chart
Continued Insistence on using red and red based colour auras in everything is punishing to people with red colour deficiency (AKA one of the most common forms of colour blindness)
How is this supposed to encourage people to play the mode? how are players supposed to not feel like this is a slap in the face?
If you want to get people playing arbitration my suggestion is
with the increased enemy level scaling restore drop rates to standard as well
Remove damage and ability negation from the drones, replace it with selective damage type reduction + one additional drone type that negates target affecting warframe abilities, this will force players to use a mix of weapons to bypass the drones, encourage varied and intelligent play, not just bring your biggest weapons on the tankiest frames and see how long you last.
Remove the reliance on red colouration, have affected enemies pulse noticeably or something.
