It is okay to increase the difficulty, but the standard and reward should follow to fit its difficulty. The revamped Gollux, even hard mode is somewhere between CRA and hard Magnus, and Both CRA and hard Magnus are weekly and instance or partly-instance loot. Revamped Gollux is one of the hard bosses now, it should have something that every hard boss has. At least, the coin drops should be instance to encourage people fight in party. It is really exhausted to fight the current gollux along everyday and up to weeks and month to get accessories.
