Powerful Spirit Blessings - Improvements

Hello, there is thing that should be change in a snowflake event. Indeed for the title "Powerful Spirit Blessings" (id 530947) , you need a group to be able to kill it BUT the problem is that only the person who summon the boss get the title so thats unfair for all others ppl in the party. Could you please change it so the title can be obtenable by all ppl in the party so we don't have to summon and kill him one by one.
