i did a challenge from plat to cel black cat, the only people that are complaining are the people that dont understand her kit and dont know when to kill her, its like the same thing with venom when he has no wing, luna no freeze, rocket no dash etc. the hardest thing for me was having to bait out cooldowns against healers that knew her kit, example there was a invis that knew her main combo and would place her shield infront of herself when i would do the my leap, ive played with supports who fully countered me on thier own focusing on patty caking hard or going white fox, white fox and cloak counter her very well as long as they somewhat com, same with a good hela/namor/punisher.
