Teef I have to disagree with you on the x ray thing, Reptile has an awesome x ray that shuts down zoners completely and it gives you a crap load of advantage on hit. Im starting to think reptile doesnt need breaker at all unless he is fighting against cyrax, ermac, or corner with more than 50% dammage.
By any means I'm not an advanced player at all. However, I consider myself pretty knowledgeable, because I stalk MK9 info/forums and examine. I'm slowly getting there.
You would burn 3 meters of a bar, to do what like 30% damage? That's absurd IMO. The only way I see a naked X-ray viable for Reptile is if the opponent has a breaker, and low health, than you would use it, possibly armoring through their projectiles because they are mostly going to be trying to play keep away to stay alive. You can't follow up much after Reptiles Xray either if I recall correctly, you can dash, I think at most. (Unsure on this I KNOW you can do something after the Xray, but nothing huge)
Doesn't need breaker- Absurd, everyone needs breaker. Just because he's fighting Cyrax who can reset doesn't mean you save breaker exclusively for Cyrax. And it's not all about using meter only when being damaged, which is what I seem like your line of thought it. MK is not all about combos and damage, people should drop that crap.
You can use EX Dash to get out of corners, you don't need to waste 2 bars and break, well unless you're caught, but that's stupid.
You can use EX for dash, I believe EX Green hand after EX dash does something, Teef might know better.
EX slow ball is great for set ups after 321 or getting in on a character. You can even cancel balls to play mind games.
Not to sure what OKI means, but Teef covered it, I don't exactly recall, but it was good from what I remember. My memory is shitty.
And I'm an average player. Breakers are Godlike. You can do a normal BnB and get as much damage as a Xray, more so with a single bar. Haha.
On block- 321 EX Dash, D+4 Acid Hand, mix up, I think if caught can be followed by slide.
String- 1221 F2 EXFB 321 Slide.
