sounds good!
could you be more spesific?
are there any spesific tpyes of melee you have to win like do they all have to be 5 novice wins, 5 veteran wins, 5 musou wins or could it be 5 mixed wins?
would there be any battle conditions settings that would effect this?
would the item or items in the reward chest be of more superior quality and/or quanity if you won veteran matches compared to musou or novice modes or is the item/s recived based on distribution,tech and milatary experience or totally random?
