No 1hr survival (or anything beyond 20mins), no friend/clan stuff, no ayatan stuff. More using obscure weapons/tactics to do basic missions, melee only, sniper only, complete missions quickly, stealth challenges (no lua spy please). Encourage the use of not so used warframes/weapons perhaps.
Am I the only one who thinks needing to be max rank to do the heist thing is a bit much? It's a load of standing and the daily cap just makes it so tedious and long (yeah I know fortuna's been out a while but still)
