Considering no one said that, you're obviously just mad from the other topic.
As another lancer said, it's not worth the hastle and probably best to just pick one or the other for that situation. I believe it. It doesn't look like it would on paper, don't have to have the abilities to necessarily come to that conclusion. You just have to be a believer in the null hypothesis sometimes, not a believer in every little thing you do mattering just because it's you that does it.
"A debuff is a debuff" is a logical fallacy. Sometimes one more doesn't matter. That statement depends on an all or none mode of thinking, when that line of thinking is more detached from reality and thus irrelevant to the truth. You have to ask what your debuff is actually worth, because it is costing you something. Not just "is it there or not."
Sometimes a debuff is just meaningless wheel spinning.
Life surge may be a complete waste of stamina compared to lancers equipping disorient and contributing to keeping it stacked to x3 with that stamina. I kick up a disorient II at the start of fights while on lancer. Not as much hate as a token life surge, and I bet that disorient x3 blows life surge out of the water if two other meleers kick up and do the same immediately.
Then you have to ask yourself what is the benefit of life surge debuff on a disorientx3'd mob? Probbly nil.
