If there are currently no plans to adjust this, then at least give the rot method a purpose. A reward, a bonus, an achievement, something... otherwise what's the point? You might as well remove all of the ADS mechanics since rage mode has become the standard amongst the player base. I personally prefer to deal with the mechanics because I feel it makes the fight a little edgier and it takes a little more degree of skill, but it's hard when ppl leave your party after learning that it isn't an enrage party (despite my specifying in PF).

All I'm saying is give dealing with the mechanics of the ADS a little more bang for your buck. If you complete the run within the time limit before enrage, maybe reward that with two chests. If you're trying to do it with a pickup heavy party, and you don't wish to endure hours of wipes b/c one or more ppl struggle with the mechanics, and you just want to clear the damn thing, then make the enrage method only reward one chest.
