If you look at the character, it's very obvious what Paulo was trying to do.
F21212 was CLEARLY meant to be a punish string. Those highs are Paulo's way of telling you, "this isn't for neutral. This is for optimizing damage. Enjoy." But people aren't getting it. Same thing F21: this is a whiff punisher, guys. It's not supposed to be you're go-to confirm string. You already have a safe confirm with F4. When your opponent mis-spaces a dial combo, F21 is your best footsie tool. The krushing blow is Paulo's way of saying "wink-wink, use this string for whiff-punishing, you scrub."
Paulo gave you guys a very clear map of how you're suppose to play the character, but no one wants to see it because either A) they want 1st-world tools such as 50/50's, or B) They're trying to play the character in a way Lao wasn't intended.
This next point is probably the true spirit of the issue. "But why doesn't he get safe strings when everyone does?" His strings are all safe with Orbital. All of them. It makes his F1/F13 stagger a safe 50/50. THAT'S 300+ DAMAGE FOR A STAGGER SETUP. Now that I've typed that, we wait for someone to say, "But it takes two bars! It's too expensive." Three points...
1) Lao doesn't need meter to play his basic footsie game. Did you do orbital? Now you gotta walk in the neutral. Again, Paulo wasn't being cryptic here: he wanted to reward patience and neutral play. Lao with meter turns into a stagger monster. For the while, you're going to have to look for whiff punishes and check your opponent with F12 and D3. That won't be good enough for some people. They'll need plus frames. They'll want a combo-starting 50/50. That's not the character, though.
2) Once you've established that you're using orbital for safe-canceling, you're opponent is going to be conditioned to wait for it. You don't always have to pull the trigger on Orbital once your opponent is conditioned. You get to save those two bars you were talking about, which is good because apparently you need them so badly.
3) The people complaining about the two bar penalty are mostly just trying to disguise their actual sentiment of wanting Lao to get safe shit for free. I have zero pity for these people. In MKX, many people would have KILLED for a safe 50/50 stagger, and when lord Paulo gives one to Lao, you sip your wine and say, "Two bars? I wouldn't sully my hands." Spoiled. Just straight-up spoiled.
Finally, people are gonna cry, "But Geras!" If Geras is your problem, then the solution is to nerf Geras. That has nothing to do with Kung Lao. By nerfing the top 6, Lao becomes a SUBSTANTIALLY better character.
I do think two bars for orbital is a little ridiculous, but it doesn't ruin the character. Just play the neutral, build meter, and optimize your punishes. Lao is going to be fine.
