Why do tanks need Determination stat still when they have Tenacity?

[DaulBan]

As for determination, the dps side is more potent than tenacity. Picture it like determination gives 100 damage while tenacity gives 50 damage and 50 mitigation. And since excess mitigation in this game is considered superfluous, determination is more valued due to it giving a greater dps increase.

This, but to put Specific numbers, it takes an 1449 TEN stat in order to reduce incoming damage by 5% and increase damage by 5%. For the same amount of DET you get a 6.5% DPS increase without the damage taken reduction. It's about +.045% DPS per TEN, +.059% per DET. It's a fairly small gain, but one that adds up when you have 1500-2000 DET.
