Most games have bosses that low level players can beat - 8.7 M bosses are for level 30+..
It will be harder for everyone to get EP not just for you so your rank would not have to drop.
It is meant to force players to work together as noone can kill them alone.
I dont see it as a bad thing if players formes guild or something like that to work well together.
Reward for killing 8.7 M bosses atm is too small most players dont bother to try to kill them.
