I know Grey Havens atempted to make them harder by increasing enemies health and damage due some people where complaining about how easy it is (which if you ask me, most of them must be people with 10K hours on the game, a BK set with 3 MAX UV on each armor and 2 mixmasters capable of the imposible, which even tho this is just an overexageration, there is and there will be players like this on any game really).
But I played a Snarbolax Shadow Lair with 4 people in elite and it's not even funny how a turret needs 4 people spaming polaris for 10 full seconds to get killed.
I feel that this change was not needed at all, that is something any developer should evade to do when they are asked to make something harder. Making more complex enemy actions, arenas or status is a way to make the game harder while still keeping it fair, increasing a number or two it's not the solution, unless you let to players choose to do that.

PD: By saying all of this I'm not trying to be disrespectfull to any player or developer of the game, I'm mostly trying to justify my idea to tune down Shadow Lairs' dificulty back to what it was before by using a constructive opinion.
