Tenacity once again, whats the numbers?

[Sylvain]

Tenacity's only worth comes from how much more nukes your healers are able to throw out versus healing you from autos. It will never save you from a very telegraphed tank buster.

I was mostly referring to boss AA eventually killing me because healer wouldn't heal me.
It is also possible they were simply waiting for me to be low enough.
It did save me once from ark morn tho.

However the gain is in fact very weak and with a competent group it will not change a thing in its current state.
