I think it is a bahamut first where gilsellers actually tried to kill guivre and not just stand in the area where he won't aggro you.
btw, the screenshots have some people from tony's LS helping the gilseller pt, ofcourse, we already know they aren't gilsellers. Prob just wanted to have fun lol. If the gilseller RDM would have BUFFED, they could have prob won...
