A feylock has little reason to care about Str and Con. A starlock wants good Cha and good Con, so you benefit from both the +2 Cha and the extra hitpoints on surges, and even the Str bonus comes in handy to get heavy armor, which you'll need 'cuz keeping both Con and Cha high doesn't leave much for your Int.
They can work just fine as wizards, but their racial benefits serve more to round them out rather than increase their class power. Their Stat overlap seems in good part designed to balance out that breath weapon power area of effect, which for a wizard is easily covered other ways.
I now want to play a slinky, sneaky dragonborn, ashen gray and breathing cold, wielding frost weapons with the wintertouched feat.
