Multiple portals for end game bosses

We need more than 1 portal for end game bosses, I think the default 6 would be great but the fight resets if you die, so you at least have a chance to see the mechs and learn the fight.

I'm level 91 and I haven't found a single citadel, my friend who is 93 found his first today but managed to die to the boss and now he has to farm yet another 200 maps to find it. Oh and there are 3 of them in case you wanna try the last boss. It's just stupid way to design the game.

They are pretty much forcing people to watch videos before hand since going to the boss blind is just waste of 20-30h of playing.
