Want a challenge take a group of casual players who have not done titan hm and teach see if you can win. Without gil attachment . That would be challenging.
Btw im a casual player who enjoys this game. I wont buy my way to end game ill enjoy making mistakes. It is fun to learn. Dont need to blow up game in a week and yes i will enjoy endgame as well bugs mistakes fails wins good groups bad groups etc ... it is a game made to be fun played to be fun.
