Take a look at Fisto's skill set. You have the following:
Offense up
Defense up
Tenacity up
Potency up
AOE
Counter attacks
Double attacks
He's extremely spread out in his skill set, and seems to embody the phrase "Jack of all trades, master of none".
This would indeed be appropriate for a Shii-Cho practitioner, especially one who's known to be extremely versatile. Like Fisto.
Making this character, I picture the developers tried to find a compromise between versatility and strength. They made a toon with no glaring flaws, and no obvious strengths either. In the right situation, he can outlast many more specialized toons, but he'll likely not outshine them.
A remedy might be to give him a "unique selling point", something that sets him apart from other toons. If his AOE attack was more reliable in granting Potency up, and if the buff was a little bigger, he could be very useful for increasing the power of debuffing toons such as old Ben and Phasma.
Maybe this will happen at later levels? I'm not sure. But for now, I think there are other toons to focus on. And all the bugs.
