Hello, i am a relatively new player in MKX and in MK world.
I started playing with scorpion inferno as a "beginner character". I play with my friends and being able to play good matches my purpose.
So i am not pro and may post here and there in the future (and try other variations of Scorpion - I like him and don't want to play with other top tier characters especially that is good enough against my friends, yet).
I try the combos of course and I must say that "214 Tele 21 MG" is working pretty well. There are excuses which was mentioned above. Close to the wall and after too many strings. But after a flame heel + spear i can do it pretty well.
For me the bigger challenge is the 214 Tele 21 spear because my hand is so lame and can't execute the spear properly yet (i see in the practise that i don't imput the "back" properly but i wanted).
As I see inferno is not a popular character anymore. I like him very much and very funny against my friends. They respect the minion and it is always fun to suprise them. We are not pro players but we play fine games.
I can't do the vortex due to that execution problem yet. Sometimes I can do it and it's very cool. It is good they are not perfect either.
I must add that this guide is very good I try to implement the block strings now. I don't have good mentality for pressure maybe that's why i like scorpion inferno more than the "op" pressure characters. I feel better at distance but sometimes it is good to run and throw.
