Domination is honestly not a big deal. It's like a term from the stone ages where people happily folded AJs to a single raise.
This is something I learned from C9 -- the odds
of flopping top pair and being dominated are about the same as them flopping a set. That is, if you have A3 and are facing AQ, there are only 2 more aces in the deck. If you flop an Ace you should feel pretty comfortable betting it. This doesn't mean you are going to get 3 streets of value but honestly how many hands do you get 3 streets from when you raise UTG?
I bet most of you will find suited Ax is a profitable raise from any position.
The nice thing about FR is that people fold AJ and worse all the time to UTG raises.
