Gamora's buff is live and...
She's actually better but also the same. First, credit where credit is due: the animations look and feel great. She feels very smooth to play and her new heavy attack is a breath of fresh air. Onto her abilities, they are mostly the same but they feel better. Gamora's issue was never her damage output. It was her lack of utility and more importantly, her ramp up. She was heavily dependant on RNG and spamming her heavy attack which made her very difficult and impractical to play. Now, her chance to gain buffs is higher, they last longer, and her new heavy attack feels much better to throw. She's able to ramp up much quicker and can access her miss counter much sooner, especially now that you only need 8 buffs to stop miss. The team I recommend is Mr. Fantastic, Angela, G2099 and Cap IW. All good champs that synergize and support Gamora.
This buff addressed one of her main issues and made her useable but I'm not sure how much you would want to use her. She is still very light on utility and her ramp up, while easier, will still limit her in harder content. This buff doesn't bring anything new to the table and really just makes her a better version of her previous self. I find her much more fun to play now but I can't see myself using her in any endgame content.
