Most field bosses have 4h respawn time and is to easy for a group of people to monopolize and hoarding all the loots by themselves. I suggest to make the spawn timer random instead so you can’t camp the bosses, for instance 3-5h.
Also change how the loot is distributed, instead of highest damage done by party/individual gets loot. Make everyone who participate to have a chance to get reward as long you contribute X amount of damage. Or change that if you are 20 level higher than the boss you not able to get anything. However some restriction have to be done.
Right now I dislike the concept, the highest level+best geared group gets everything, go around and take everything all low/high level bosses. I think everyone that contributes should have a chance.
I don’t mind now in iCBT, but need a change when we get open beta. Because even when we have more channel in the future. People just jump channels kill everything and have the timer just for themselves.
Edit: Also it will be less crowded.
