What do you think about this rbs spawn?

For example some guys can not be there for this time which you set to the raidboss like AQ/BAIUM/VALAKAS etc... because everyday they are not near the computer in the same time.
A lot of raidbosses are in the same time like the others..


For me would be better to change the spawns somehow or set them normaly.


What do you think?
