WARFRAME AUGMENT BUFFS PART 2
In Update 31.2, we buffed a number of underused Warframe augments. The time has come to continue this work! This batch tackles Warframes from Loki to Rhino (of which there are surprisingly many!). We have increased their viability in missions, which we hope will  encourage more build diversity.
