And you don't think it's leader abilities? I know off the top of my head we got Lumi, Old Ben, Dooku, and a few others that grant sufficient dodge as a leadership bonus that you're gonna notice it. And, not to be a down, and I'm speaking from experience because i Used them (and still consistently use Bariss for GW) that Barriss and JC don't have a great batting average at anytime in their careers.
I also know being even a few levels below the target you're hitting, the more you're likely to get dodged. And it's a function, it's not linear.
I don't mean to defend dodge as though it's not an issue, but a believe, if all accounts are equal (which they're not) it's not as noticeable or doesn't feel like a problem. Don't give up on your heroes. The grind will always be harder the higher we go, but I bet if you focus up a few characters in gear and level, it won't feel like you're as trapped.
