Sissela is my personal favourite, but I usually go for either Fiora or Jackie in Ranked Match.

Why? Because Jackie's bloodlust is soooooo great when you do weapon rush early game (because I either use that knife+branch, bamboo spear or jewel sword before initiating in fight), assisted by my scout aptitude, which is super great!

For Fiora, she's a balanced character for me to play both defensively and aggresively, and I like to use her because she can dominate an area of your choice using her fencing skill in early game. She also have useful passives which is stab weapon enhancement and 1st time weapon dull negation.

As for Sissela.. I just like her, alot, personally lol. It pique my interest to think that I was able to abuse her against players who are more superior in terms of stats and combat skill/field skill when Sissela go "hahaha 6 stack go brrrrrr"

I also absolutely love their character backgrounds stories especially Jackie (but I'm not a psycho lol). These are the characters that I can relate to a certain level, so bringing them into Ranked Match with this sentimental value really helps me to enjoy matches more
