No its not. If they play a tactic with ressing the tank for each breath in p3, then you also need to save 4-5 battle resses. Just because 1 of the guilds (exorsus i believe) happened to have a few spare resses at the end, doesnt mean they had it every single pull. Just imagine they would need to wipe everytime someone dies in p1-p2, because they need the resses for p3 breath.
You simply just cant say its the same thing.
