For the sake of trying to make the Escapist talent worthwhile to take so do i agree that flee may need a change.
But beside that, in my opinion it is your choice to flee or not and therefore not really a problem, for me it is similar in how you can take one man army to try make things more challanging for you or explorer mode to make things more easy, or the choice trying to play a mid maxed party or a more challanging approach where you dont play with a classic healer in the party.
If you choose to flee from combat to make the battle more easy then that is ok, but that is your own choice, and i dont see the harm to have that choice avaible.
