Who exactly gets to deem this 'enrage'? I'm pretty sure this method wasn't envisioned by SE, but the track record pretty much makes this ok.
If people entered turn 2 with this method before we all figured out we could do with 2 tanks and swap stacks and pass rot around would people still be complaining? "omg we can speed run turn two and don't have to wait for the 62 minute mark to fight it! 10 minute clear!!"
It's different but within the mechanics of the game, deal. I love there's more than one way to do these instances:
Solo tank cad? Great it's been done and yoshi said its ok!
Run WP in 10 minutes? Have at it it's completely cool!
Wanna kill Titan with 3 healers and 1 tank? Wanna kill Titan with 3 tanks and 1 healer? It's been done and the game didn't die!!
Just deal people, if you wanna find another way to kill ads, fine... Do it and cope, stop the complaining finally, it seems never ending on these boards.
