Is this a bug? Ahsoka Tano's ship doesn't dispell "taunt" while it is reinforcing.

Wedge's ship will apply buff immunity when it reinforces. That doesn't remove taunt, but it can still help as other ships (like slave 1) have the possibility of removing taunt, which will then stay gone if it's done while Buff Immunity is applied.

However HT also cleanses itself of all debuffs whenever it uses its basic, so once you bring in Wedge you have to dispel right away or it's useless.

Still, it's better than nothing, and Wedge is easy to get.
