User blog comment:Skipaleeto/How powerful with Gold characters get before original characters become obsolete?/@comment-28140789-20160614103842

There is a short answer to your question; I will give it at the end of a long diatribe.

Diatribe thesis a: The new Superman and Aquaman have 2800 base stat total--that's 200 more than the pne previous record-holder, that's crazy. Aquaman, however, I think is somewhat manageable, but releasing him after Catwoman/Arkham Knight is very annoying.

Diatribe antithesis point a: Priorly, augments have generally served to benefit the older characters more primarily, although some newer characters would scale up the effect of augments. Often these would be weaker characters, like Solomon Grundy/Boss (who can multiply increases to base attack as much as tenfold), Doomsday/Containment (who gets *5/2 investments in health), and Cyborg/TeenTitans. Others, however, are threats in their own rights: Deathstroke/Arkham Origins scales up augments in all sorts of ways, for instance.

Diatribe synthesis a: Superman/Injustice 2 is ridiculous, as his passive scales up the already-highest base health in the game and the former-record highest damage in the game.

Diatribe synthesis a subpoint: Even releasing a character with 1500 health is ridiculous.

Diatribe conclusion: NR has released a problem that can only be solved with a large program to balance everything or with a large nerf to Superman. The only way this character can be one among a balanced field otherwise is if a whole new field is released.

Short answer: they could make it so Killer Frost/Regime's passive works against regen. It doesn't have to be the same 90% reduction of enemy healing. Still, she's only one character, and is comparatively weak absent her passive. You can't force teams to carry her.

They could also make a Batman with a kryptonite effect, who would reverse the effect of stat-modding passives--or could reverse the effect of regen, that would do....
