It's kinda complicated to double up when they implement the Operator, make some complex and well tought content like Eidolons(enjoying is totally personal) and keep getting complaints on foruns about people who dislike it or can't bother to get good at it.
The "I want more Warframe-Warframe" or "It's too grindy" is a constant, be it on Operator, Railjack or Necramech. I find it a pity, because I like those three "alternative-Warframe" contents.
