In other games, the Fragile Speedster can be tough to control while the Mighty Glacier is easier to handle. Some games tout the Fragile Speedster as great for beginners, while the Mighty Glacier is for experts only. They may have trouble dealing with characters whose skills are more extreme than theirs if they're allowed to press their advantages. Whether the character retains their usefulness as the player's skill grows depends on how much the game rewards versatility as opposed to pure power, but the Jack-of-All-Stats is almost never the best character in any given game or a Game-Breaker.
They're also a solid choice for advanced players who want the flexibility to exploit an enemy's weakness, no matter what that weakness may be. Quite often, this character is the baseline to get the hang of the controls, since they lack the extremes that might trip up a novice. Their biggest strength is their lack of a glaring weakness, and their biggest weakness is their lack of an exceptional strength. Strong but not The Strongest, Fast but not The Fastest, Tough but not The Toughest. The Jack-of-All-Stats is a member of the Competitive Balance lineup who is competent but unremarkable in all areas.
