I haven't play the game for several month, just came back few days ago.
I orginally have a pair of yellow KM AA gunners, lv120, and they can use HH.
then , I bought another pair of lv 93 KM AA gunners from the market , but they can't use the HH, means there is no ' Gun' ability for this pair....
is this a change in some path....? thanks.
