As a 5e player, I still understand.  I'm currently doing the Princes of the Apocalypse Campaign with a few friends, and I rolled shittily for stats while our Blackguard got 20 on Dex and 18 on Str.

On the plus side, I figured out I can bypass rolling to hit by grappling and exploiting Barbed Hide.  So there's that.
