Her Sig ability must not be a Reason to Lock Her Damage As of now Gamora is one of the weakest champs in game.. the only good thing about her is her guranteed Crits on Specials whish is still weak bcz of this cap see this :
Supposing as of a 6* R1 Gamora has
( 1916 attack rating / 202.7% crit damage rating/ and under her crit buff that adss 1366 damage rating )
Special Attaques ( No Cruelty vs Cruelty Buff )
SP1


Sp2 ( whatever damage is doubled bcz sp2 has 2 hits)


Light Hit


Medium Hit


Gamora has one of the most high attaque rating + crit damage rating in game it's impossible that she delivers such weak strikes under her special attaques along with her cruelty buff the minimum she can deliver would be something above 10k in sp1 and 20k in sp2
Another contender whish is magik that has the same attributes values ( nearly ) but same 202.7% crit damage rating delivers
Special 1 Crits Magik (202.7%crit damage rating) = 3354
Special 1 crits Gamora (202.7%crit damage rating) + cruelty buff 1366 + more attaque = 3090
Special 2 Crits Magik (202.7%crit damage rating) = +10k
Special 2 crit Gamora (202.7%crit damage rating) + cruelty buff 1366 + more attaque = 7.8k
Coming back for her sig ability whish's the only reason i can think off that made this cap exist there are champs that deliver more than 700% of her crits and it's a 1 time per fight ability so do the right thing and bring her to life bcz she's soo weak as a 6*
7.8k x 7 = less than 60k 1 time per fight
make her special attaques good and cap the damage dealt by her sig ability to something like loki's
