BASHMAN
Basic Action Games
I like seeing that the versatility to combine options so far is working well in this edition. This is not the typical build and has some advantages but also leaves a few things on the table because of the mechanics, Rage and Deflect for example. If you are okay with it than I say game on. Some people will sit and calculate this damage over that damage as in two handed weapon vs. two weapon but I think deciding on what works for the "character" is the way to go and that is usually how I make my characters. If we always just build for the toughest combination then variety quickly falls off.
Well, actually, it all has to do with "reskinning" the action. One way of describing the effect of her rage, or 'battle trance' is that she is AUTOMATICALLY deflecting all the attacks (which is why she takes half damage from them) since Deflect is just some damage reduction anyway (which uses a Reaction, which you can't do because you're raging; but you also could say you can't deflect something twice, and since she is automatically doing it, there is no need for the feat).
So you might find the feat worthwhile to use when not in Battle Trance, just be aware that when you are in battle trance, you can say you are blocking attacks; in fact, depending on the attack, you may be even better at it, since you seem to do it without concentrating on it.
