Exp lose

I like playing games like this without using any broken build and watching boss fights guide, but after you reach level 70 this start getting harder. Exp lose its too big, so you have to start building your character to one shot everything. Up to level 70 I enjoy game so much, especially boss fights. But now I have to use build to not fight boss for longer then 10 sec. losing all boss mechanics and fun.
I did try to go for boss fights with normal build always after I level up as then I have nothing to lose. But as I’m getting closer to level 80 it takes too long to wait for boss fight. Forcing me to use broken build to kill everything fast. This can be fun for little bit but now is getting boring, I would prefer to experience all fights mechanics. You guys spend lots of time to design boss fights and then players one shot them, make no sense.
Just remove xp lose and let us enjoy fights the way there where intended. There are still going to be players who like easy but there is big number of gamers who like little challenge while progressing thru games.
With current system you can go from 99% exp bar to 0 in few minutes stopping your progress

If the ascendancy trials weren’t in the game this would be my least favorite mechanic, once you hit a wall in end game it’s hard to pass by getting more power because you die and lose xp. You can run lower level content that takes forever to level or try to get lucky trading. It needs some work. Not sure why they thought this was necessary
