How do we submit "bugs" if we have no idea they are bugs?

As a Pathfinder my Evasion Rating also grants Elemental Damage reduction.

It doesn't say hits... it says elemental damage reduction.

That means Elemental Damage is reduced.

That means that burning ground is reduced.

I step on burning ground in a map and i take barely any damage. Great its working!

I step on burning ground in a Azarian and die almost instantly.

Was it burning ground that i died from?

Was it a boss ability that looked like fire but was actually physical or something?

What was it?

If i look on Azarian, the Forsaken Son on POEDB and see that everything is fire... but I'm dying extraordinarily fast in comparison to literally everything else fire related in the game...

Is it a bug... I have no idea.

This is a beta. We are in beta. We are beta testers. We have no ability to test anything because we have NO KILL LOG. Why do i have no idea why I died... in a beta... and then I'm just supposed to say... I think this is a bug but i have no idea because i have no way to investigate if it was a bug unless i literally burn my own currency in game to get maps, and try to find this dude, and then go in to die again... just to see if it was actually fire. THEN report a bug? WTF no.

A simple... You died to A, B, C, D damage types, you mitigated X with armor, Y with block... Whatever.

Then at least i know... i died to a ridiculous amount of fire damage that doesn't match anything else within the game... so i should report this as a bug.
