Went to Halatali hard mode with a tank, 2 dragoons (me being one) and a healer. Tank accidentally pulled too many adds and we quickly tried to wipe as fast as possible to prevent the tank from dying. Nobody died from that big pull of adds and that was just the start of the dungeon only. Healer got mad. The tank pulls another one small set of adds before the first boss and he understands his mistake. Healer stopped healing everyone cus he wasn't happy and everyone died. The tank apologised for his mistake and left the party. I scolded the healer before i left as well. He wanna be angry fine. That is not how you suppose to play. You don't like it than leave. That player could be a new tank or he forgotten the equipments are all capped. Really disappointed at the healer childish tantrum.
