I do agree the changes to the hunt can't even be called a band aid fix . with B rank out of the equation, people are swarming to the As and instant pulling so they get max credit.
Was bad enough before patch with people just pulling as they turn up, now it's a 100 times worse.
A better fix would be that if your not in a party as long as you do enough contribution you should get max credit.
Their are times like queuing for ST etc that you cannot join a party and being able to still get credit outside a party would suffice, but killing an A rank, blowing all cool downs and doing more than most actually there and getting near zero credit is a joke.
