First of all, i've been away for about two years now, so there's either two situations: There's easy and hard world bosses, though i've only found the easy ones since I came back (in which case this only applies to the easy ones), or there really are only easy ones, in which case I refer to all of them.
Regardless of the situation, it feels like World Bosses are way too weak, allowing basically anyone lv.150 to solo them for a weak reward getting at most 30 ec worth of loot.
I vaguely remember there being much stronger world bosses, if that is the case, why do the weak ones still exist? Is there a reason to not replace them with stronger and more valuable versions?
If that is not the case and all bosses are like that (though I highly doubt that's the case), wouldn't it overall be more fun and interesting to have challenging bosses with great loot that could only be obtained by an entire squad?
