Out of all my glads only the shadows have a huge problem with winning the gauntlet runs.
I'm talking about nightmare gauntlet, with different shadow builds, all of them had or have reached the top 10 primus spots and were HoL slaves.
Its not impossible to win some gauntlet runs but only with huge amounts of gold. Had one offensive shadows, one defensive shadow and one aiming derectly at exhausting the opponent.
All other classes had no problems at all even with blue items... okay sometimes my counter theatric is screwed vs some match ups but its rare.

My impression is that shadows aren't build for teamfights there are only usefull 1vs1?

They straight up die during gaunlet fights... i never seen other glads dying

Have someone a solution on that topic or should i just retier all of them and never ever use a shadow again?
