If I had to suggest an alternative to our current talents then a choice of execute spells would be nice, I don't want anything like a pet or static buff to our damage that simply requires a button press before the fight starts (or no presses at all), I want something that would interrupt or augment a mage's rotation in the same way that these talents do.
They are designed to limit mage mobility and add extra depth to the class, any replacement would have to do the same.
