As to your other point on BHR, there are some toons whose Taunt also states they can't be ignored so there for it would negate BHR ignoring it depending on the RNG rolled during that turn. I too have experienced that not only with Boba but with Commander Luke aswell. RNG is the true decider on how the turn is played out. Ive had matches where Raid Hans Shoots first ability is done second to strangely a really fast opponents toon. They get their turn off first do to RNG.
