Hello I have this problem with doing the combo right and I can't do anything about it... I did read some stuff on the internet but it didn't help. It says I should do Dragoncall 4 consecutively against Hajoon then use Bombardment to confirm that the Dragoncall cooldown has been reduced... I am trying but it wont work... What should I do? Please help I am really desperate been trying it for an hour q.q
