Reason why I posted that vid. He reminds me of the time when I played Mafia Wars on FB. They call these people the "Serious Business Players". You find these players literally EVERYWHERE.
Plus, the boss that he means are called Scoll Scolipede (those things that look like scorpions). One of my allies had one up yesterday. Those things can be easily nuked, since they only attack 1 girl at a time and these things give 1000 equipment seeds
I killed raid bosses from allies by attacking them twice too, didn't hear them complain. The main goal is to BEAT the raid boss, not "let's play a game of who can do the most damage to a raid boss".
BTW, How high is the chance of getting an Ampy via the normal gacha? I just got a DEF Ampy...
