214 was not unsafe with Hellfire, his pressure involved ending it in FBC, making it +8.
Now the gap is BEFORE the last hit instead of after it, that last hit did more chip than the other two hits (almost as much as both put together) and the active frames hurt his Flame Aura pressure.
Here's some maths for you and a display of how this translates to his gameplay. Hellfire at the moment uses [FA, 21 FBC 4xxTP] as his combo ender and goes straight into 214 pressure. His first two hits do 0.75% chip each, for a total of 1.5% chip. His third hit does 1.25% chip, and the active frames get you your first tick of Flame Aura pressure (1.20% chip). The gap coming BEFORE the 4 instead of after it during the FBC, puts 2.5% of Hellfires currently guaranteed chip - AKA he loses about 2/3's of his current guaranteed chip after any combo.
To put it another way, if your opponent backdashes your gap, you used to get 4% chip, you now get 1.5% chip. If your opponent doesn't backdash, you used to get 8% chip, you now get 5.5% chip, it continues on. Test it yourself. His blockstring pressure is nerfed from what I can see from here, but let's see what else he gets instead. At least 21 FBC 21 breaks armor if used immediately after a FA 21 FBC 4 xx TP ender, so thats a plus. Pressure not as nice in the neutral tho
