Is it me or have they added difficulty scaling since hutt cartel or has it always been there.
Reached 55 on my sages and when i enter quest areas it comes up that difficulty of this phase increases with group size.

I just did a mission called No place left to hide, part of the seeker droid mission chain.. so anyways in my group of 2 against boss he spawns 8 big adds with high health taking all i have to take just one down then i keep wiping.
Then i go in solo and its basically 4 much smaller adds with almost no health and i do it easy.

So ye just a bit confused if its always been difficulty scaling in quest instances or its new
