if the problem is that you wouldn't want to see this the 9th time when farming it or whatnot, just look to alexander savage. The alexander raids had neat run ups in the normal mode, then in the savage version had the zone-in point right before the boss, allowing you to get in another attempt straightaway. Also, take a look at T11. That run up is probably one of the coolest in the game; and I think a lot of flavor is lost without environmental setpieces like that or the city in alexander.
