T4 Pinnacle unique drop rates are too low

I really feel like the drops from T4 pinnacles are so unsatisfying at the moment.

I understand the need for chase uniques but I'm at the point where I've run dozens upon dozens of all the T4 bosses besides arbiter and I basically have nothing to show for it.

I have 3 Diamonds, two from Ritual and one from Xesht, all 3 totally undesirable rolls.

I've not seen a flask yet after focusing hard on delirium and Olroth.

It might feel exasperated by the fact that pretty much all of the boss uniques are kind of useless or have been hard nerfed, so constantly getting the t1 unique drops at t4 just feels so unrewarding and then having to further hope for RNG affixes on the scarce amounts of diamonds just sucks.

I don't expect it to be dropping every single time, but right now theres just no joy after pushing this far into the difficulty level.
