The short range has been a big handicap for the wizard IMC. If he's close enough to fire a scorching ray, that puts him well within charge range. And at the levels where this spell is worth casting, he's still so fragile that any threat of physical combat is Very Bad News.
An enemy who's already preoccupied in melee won't likely charge the caster, but firing the ray into melee means -4 to hit and a chance of frying another PC, which wouldn't exactly be a useful outcome.
