jt4mtb nails it again, in my opinion.
You're exaggerating BBCS combo damage and underestimating SSFIV combo damage. I really don't know what videos you're watching. Outside of Litchi corner combo rapeage, very few pure combos take away half the health of an average HP character.
I'm talking pure combos. Not resets because they don't count. If you're sticking to your guns about resets being like real combos in BBCS, then it's really just not worth arguing. I'll just leave it as... if it's a red combo, it's a real combo. If it blackbeats, it's not. That's the definition of a combo in the literal and figurative sense.
You may just not like what are called "New School 2D Fighters." They tend to arguably have more limited defensive options.
