I really am not sure what you expect, hard mode raids always only ad 1 additional mechanic to the fight in an effort to increase difficulty. A side from this no re-spawn's does up the difficulty as well. For example, look at kings fall, Warpriest was the same except he acquired taken abilities. Golgoroth was that same accept one player got the buff that blows up like a cursed thrall. Oryx was the only real change to the fight with the 4 knights spawning. Vosiks fight - you have to throw 6 charges and monitors are harder to kill and door are closed most of the way making them slightly harder to get in(for most players sliding in is easy). If you hit all 6 charges Vosik's sheild takes the same amount of time to take down as on normal. Zamboni - I agree this felt like the same fight, adds just kill you a little bit faster. Aksis phase 1 - adding the turrets is fine as it adds in the difficulty of always having to pay attention to the turret. Makes you think about something else during the fight. I personally would of like to see the phase go 3-6-9 with the charges you have to throw with no increase of time. This would force your team to communicate more and work a little faster. Aksis phase 2 - I felt like this fight was nice, more servitors to kill with the time to throw charges seeming to be the same. I do feel like the Turrets should still be there during this fight. Also I feel that Aksis should continue to shoot at us during the damage phase. Keep in mind that Bungie designed this raid for the casual player. they wanted it to be a challenge for the casual player but be able to be beat by any one. I think challenge mode will introduce some more difficulty for the players who feel the raid is to easy. I would like to see something such as aksis phase 2 for challenge mode be along the lines of having to super charge every teleport. At the end of the day I feel this raid is very fun to play.
