The problem with allowing Turn 2 Rage strat

[Sapphic]

While designing fights to be tackled using multiple methods definitely is a good thing, common sense tells you that the enrage strat was not on the list methods, that SE designed this fight for.

The enrage timer was not designed for people to go on a cigarette break to deliberately wait for its expiration. The debuff on the tanks was put in place so bringing 2 tanks (as required by the usual party setup) actually makes sense, as the debuff requires tanks to swap emnity. You think the beduff was put in place for people to say "Well, lets just not pull until the last click has begin, so the debuff doesn't stack too high on the tank?

Riddle me this:

If ADS wasn't supposed to be able to be killed while enraged why didn't SE make enrage a one shot mechanic?
