Whatever scaling factors were magnified with that update, really made the tower untenable.
Today level 71 met floor 8 level 74 barb team. Boom. Two teams dead. Give up time.
I am not a top tier pvp'er in the world, there is no way whatsoever I can take on great runed defenses 3 levels above me.
Maybe someday when I can rune elite, but I'm skeptical.
(writing this not just for myself but for the good of the game and for the segment of the user population that feels this way. Personally, its just a mobile game, I can always do something else.)
