Is it worth jumping guilds for General Kenobi?

There's a difference between being loyal and playing with people who simply don't care. My guild also couldn't tackle HAAT months ago, but everyone listened when the leader/officers asked them to develop certain teams, listened when we were told what teams in which phase to use etc. After 2 failed attempts we asked a friend, who had deeper roster to help us out. He did about 16m dmg the first time, 8m the second time and by the third time we began HAAT with him in our guild he simply stayed and watched. So if you're at the point in the game where you're ready to farm HAAT but your guild is still struggling with the normal one -> yes move to another one.
