Disagree. If you've got more than the two percent miss chance, why are you using his skill and Prepared?
Maybe, give it two attacks instead of hitting twice if getting dodged is that big a deal. I don't think it is, even with Bastila roaming the streets.
The prepared bonus is double damage (read-double the heal) and also healing chewbacca and also protection up (possible team wide) and also getting the skill off cd faster. Getting all of that off of a tank special is the prepared bonus, I don't think it needs to ignore defense and be unavoidable. Pick a different target, or if it's the last target the prot up is probably enough and is not tied to the attack being successful.
I don't think everything needs to be unavoidable. What's the point of dodging in the first place then? Unless another team is dodge heavy, making JTR, Bastila, and newteam with heavy foresight, then we should be good with what we have rn that is unavoidable
