Garcia has some great vocalizations during his matches, specially those bloody wars the JAS has been in, but in terms of actual promos he's not there yet. Shows promise, but still nothing to justify that much screen time when people like Starks were begging for more yet were relegated to the way less popular show Rampage. The biggest problem is that after all this time, he's in the same place as before. Why?
As for Yuta, the issue is not him being used, but how he was used. He got over being a human punching bag to Bryan and Mox. He's not nearly on their level, yet in tags he was treated as someone who could totally hang, and not as Shingo Yabuki. Those tandem elbows the BCC did always bothered me. Other than that he's alright IMO.
