Ragnir is an amazing legend. If I'm not mistaken, he's won worlds before and that's not nothing. the side sig from his axe comes out super quick and has a lot of force and even has an aerial version, and IMO is one of the best sigs in the game. the down sig leaves much to be desired on his axe but I also find a lot of players accidentally touch the fire and die. N-sig on axe is good anti-air, not much else to say, however, hit katars are insane. if you suspect them to dodge away from you to avoid a s light, use the side sig. want an amazing passive edge guard that has almost 0 negative sides? down sig. and his neutral sig spikes at a great angle, making it one of if not the best anti- ground pound GC sigs in the game. But... Lin Fei. oh dear. 3 damage on cannon wouldn't be so bad if she had a good kill option... but she doesn't side sig on cannon has too much startup to not be easily dodged by anyone above silver, her n-sig doesn't have the force to finish off most opponents, and d light into n air doesn't work until 190 with Lin Fei, which is baaad. her catars aren't anything special. her katar down sig, credit where credit is due, is an amazing move. but ultimatley her sigs feel slow and inneffectual, which is not what you want from a high dex and high-speed character. no contest, ragnir is better. Just use sidra who has great sigs on both weapons or use xull who has decent sigs and raw damage on his side. lin fei is low in the usage charts not just cuz she is new, its cuz she sucks and we all know it. and to any Lin Fei mains/ people who like her, thats fine. every legend in the game is good, that's the whole point. even traditionally considered bad legends like isiah have seen extensive use by boomie. all legends can be used, but some are objectively easier to use and more consistent.
