From a purely combat standpoint, many enemies are going to notice “the bigger threat” and gun for it. This leaves room for other (possibly less powerful characters) to make meaningful contributions on the battlefield without going toe-to-toe with the baddest foes on the board.*. This happens often in RIFTS, which is notorious for not giving a damn about balancing out PC power.
OTOH, some point based games will leave the non-combat focused PCs to shine in other aspects by simply letting them allocate their points elsewhere. In some old published HERO write-ups, Superman and Batman might be built on nearly identical point totals, but the bulk of Batman’s points are in skills, talents, perks and real world assets like bases, labs, vehicles, gizmos & gadgets, contacts & informants, and, of course, wealth.
* I’m reminded of the final issue of the DC miniseries Manhunter (the Paul Kirk one). He and Batman (and others) are assaulting the secret base of The Council (evilbad organization) that created Manhunter in the first place. Manhunter mentally notes as they’re all fighting through this army of defenders, Batman keeps going after the biggest, baddest foes on the battlefield, while Manhunter- as close to Batman in martial prowess as makes no narrative difference- mows through mooks at a ridiculous pace. In Manhunter’s mind, Batman’s tactic is mistaken because that the assault is taking place on a literal doomsday timer- if they take too long, the world is doomed, Ultimately, Manhunter is the only one who reaches deeply enough into the stronghold to accomplish the mission, which he does.
