As you said yourself it'd deter most level 50's from soloing them, but would that also deter the people who do it for fun? Because that was why I soloed them once - to see what the bosses looked like. I was wondering myself what to do with the "ops race", but I just couldn't find a better solution than to instance the bosses and discard the "ops race". In my opinion this prevents most bad things from happening. And I'm looking for a system that makes it able for everyone to say "Hey! We'll do this world boss on monday!" - and then if a level 50 had just soloed the boss monday morning, it would be impossible for these guys to do it. This system with instances would allow casual players, who don't play that much, to pick a date in the calendar with their friends and do the boss - I think that things like these would open the game for a much wider audience. But you know - it's just an idea

Earlier today I assembled 3 ops groups for the world bosses on Alderaan, Tatooine and Nar Shadaa (1 ops group for each planet since almost everyone left the group when we moved to another planet). When we got to the spawn areas we found out (by asking around) that a level 50 had just soloed them. It was very annoying since we had to wait a long time to be able to kill them. The reason why I'm posting this story here is: I thought "Well... There must be other people having the same problem. And the 50's who're soloing the bosses are ruining it for the players who’re at the appropriate level." Before going any further with this thing I have to say this: I don't have anything against soloing world bosses at all - I even did it myself once! But then again I didn't want to ruin it for other people. So my idea is that BioWare should make phases for the world bosses - Yes I know it's not just a minor thing 'cause it'd take some rearranging of the map - but hey - that's what patching's for! So instead of the world bosses having a very long respawn time, the phases should have a cooldown for each person who's slain the boss in their phase. But in order to prevent mass re-runs from different phase owners (you know where you change the story owner), the ops should own the phase so that every guy in the group gets a cooldown. This would also prevent people from soloing it and then joining a group. It would make for a ‘world-boss system’ similar to the one we see at the moment, but with the possibility for all people to do it when they want. Now that was my idea. I'm glad to share it with you, and hear what you think about it. And I'd also like to know if you've had the same problem! Ps.: What is the respawn time? Can't remember
