I noticed the same thing, scorching ray now deals more damage than polar ray.
(and frost lance even more than that, but with a save).
But I think it's fair that a single target spell deals significantly more than an AoE.
Polar ray was just severely lacking in that regard (same damage as ice flowers).
With iceberg one spell level after that deals 1d6+28 instead of 1d6+8, I've always found Polar Ray oddly placed.
I'd personally have gone for 1d6+4 per two levels (x3) for scorching rays and 1d6+16 for polar ray.
