Tbh, if you dont nerf something while balancing and only buff the weaker one you will end up where Diablo 3 is now.
Just look at some of the set item bonuses :
Impale deals an additional 75,000% damage to the first enemy hit
After casting Rain of Vengeance, deal 14000% increased damage and take 60% reduced damage for 10 seconds
Spirit Generators increase the weapon damage of Dashing Strike to 60,000% for 6 seconds, and Dashing Strike increases damage of Spirit Generators by 6000% for 6 seconds
That is insane power creep.
Warframe is (for me at least) always about
