Yeah, power boosts are, IMO, the laziest way to 'beef up' a character. Uber-powerful characters, like the Sentry, Phoenix, etc. quickly become unusable, and get written off screen or killed or have their powers stripped away (and, if they are women, like Jean or Wanda, go crazy because 'women can't handle power'...).
Plus if Ben wants a ranged attack, he can throw a rock (or car...) with 70-plus tons of force. That beats any gun ever made, except maybe the 'Paris Gun' used by the Germans to bombard Paris. He surely doesn't need another super-power to knock someone out of the sky.
