What's up everyone

Coming straight to the point: Just played the map on hard with 2 other players (we were full, but the others left for crying reasons). We killed all bosses, even the endboss and went to the next stage (where you get those asura points).

Now we got to the level with the "Madness Archdemon + Wrath Archdemon" bosses (don't know the wave number anymore). After dying a couple of times, I found out that the "Wrath Archdemon" had 474.526.624 damage attacking every 0.7 seconds. I played Bristleback, had my damage reduction ability to the maximum (around 60% - 70% if I remember correctly), I had like 1,5 million HP plus more than solid 99% physical reduction (~1,6k armor), we had multiple items providing magic immunity and he just CRUSHED me, 2 hits mostly, maximum 3 hits.

Okay we thought, you have to kite and kill him, so we (Drow Ranger, Treant Protector and me as Bristle) threw every single slow and root effect we had right into his face, but he rushed through us and literally f**ked our asses in a darn preposterous way.

Despite the fact that we surly could have blinked our asses of all the time (which leads to 1 less item slot for defense / offense and a boss fight which would take like an hour), are the damage / armor scales of bosses like they are suppose to be? Like adding millions of millions of damage, according to this scaling even reaching trillions of damage and also the armor of some bosses, which is like xxx.xxx armor? If ask me, this sounds a bit over the top does it not?

Oh and btw, how we were meant to defeat those two bosses anyway, since I couldn't tank and couldn't we kite it till the end?
