Hall of Grandmasters is very deceptive and lost alot of xp from it!

Hall of grandmasters being a tier: 9 map is very deceptive. When i can breeze through T11 maps I thought i can do a T:9 map but its near impossible. Im new to the game and this seem like a very dirty trick to get new players to lose half of their xp bar trying to do a tier: 9 map to get the atlas done.

also why is there PVP oriented stuff thrown in there when literally the rest of the atlas is PVE? I am extremely salty that i lost half of my level trying to do this T: 9 map.
