For me its oryx. Yeah i could probably go back and beat it now (been through the whole thing just no completion) and it wouldnt be too hard. But for me it was like they just threw more crap at it. The whole point was to have a mechanic to beat the boss, not 7 mechanics that really didnt need to be there. Bungies way of making things harder these days seems to be "throw them in a room with enemies...too easy? Lets add more enemies. Not there yet? How about some more!" VoG was good. Was a month before people even knew there was a cave that lead to atheon. And each boss had ONE mechanic that REQUIRED a group. Now they just throw in way too many mechanics and endless enemies and wait for people to solo it. I remember back when you actually needed a team, not because it was hard but because the door couldnt be unlocked or the boss couldnt be beaten unless you had multiple people to do their parts. Now its just meh. Yeah the machine is alright but its kinda too little too late. Just hope destiny 2 has better boss mechanics and less just throwing us in a hole with tons of enemies.
