Everybody in Shadows is dropping at the end of the third floor. The Immortal teams are OP. Those clans attract the strongest players on our server. So, yes, this is a bug, unfair playing mechanics are, and this is a built in mechanic of unfair content where players are overmatched, unable to be competitive. It’s bad enough Eternals come prepared for PvP while most players must prepare for PvE.
I suppose you could call this a whining post. Just try this way of doing things in Battlefield and see how far you get.
At least develop a mechanic to equalize, buff or de-buff, players and/or teams when Immortals enter. Solve a lot of issues too many to list here,
