Actually you can't. You can only beat final coil if you either:
A. Are good at the game or
B. Have found a group of 7 other players that are good at the game that can carry you and they accept you into their group
Fully melded i110 gear doesn't mean squat if you are dead all the time because they don't know what to do for wild charge. Someone who "P2W" all their high end gear still has to play the game and earn the skill in the game in order to win the game. The negativity of some of the people in the community kills the game way more than someone selling bracelets and buying i110 crafted gear.
