While Kabam try to rework the nodes for future elder difficult,lets try to help
They are going to change to fit new characters and more abilities in general,Even though it is a simple task in practice, I still have my doubts they will try to innovate in a different way 
The easier one is the skill,the Crit purify was perfect and the sole change was to not cut will power mastery,we already can't heal from the character changer
Mutant one is perfect 
Science bring back the previous one but include more debuffs such as Vulnerabilities, taunt and traumas (Correct me if I'm wrong but I think at least 1 of these 3 is already included)
Tech you simply include passive armor effects, you could argue the shock one is better but i think it's better to mix both
You power drain or apply a shock or Incinarate you gain the fury
Mystic you can also use the previous one but you include power drain,burn or steal when you reach a bar of power,with this some characters with less Nullify can also benefit
Cosmic instead of 3 furies, precision or Armor it's simply 3 buffs or 3 Armor breaks
I don't know what they gonna change but i realy hope they simply improve the last month nodes and  don't try to use us as guinea pigs again
