News datacrons "Necessary Means" having influence in RotE ..?

Hi,

Before them, our guild can success easy peasy in RotE for the special missions (Merrin, Reva).

But this time, we failed whereas nothing change (toons or characters, ...).

I've noticed that the last datacrons have Talia, Chief Niebit, Tartful, ... for their last level ... Is there a biasis without turning in a complot theory .....?
