The lack of tactics has been apparent since Relic Weapons were made common. When people were getting through Titan Hard without even learning the tactics, it was all downhill from there. When they introduced The Wanderer's Palace it became blindingly apparent that any other tactic other than AoE mode was going to become obsolete. Dungeons prior to 50 don't experience this phenomena. The reason is because the level caps prohibit us from being over geared in the dungeon. Everything caps in those dungeons including gear so we have to actually use tactics still. I don't blame SE for this because although they placed the mechanics in the game, it is ultimately the gaming community which creates the community norms.
