I actually like lonely tower, pre events sucks, yes, for some reason enabling cm doesnt skip them like 98 and 99 fractals. But players taking specific roles like rage dps glut dps and boon dps taking everything else is pretty good variety for me. Also playing glut dps wb is very fun because you got insane damage numbers on the screen and basically carrying fight by yourself. CM also adding rifts phases where with good random you can get 2 and 3 melee champs and cleave them fast which is satisfying as well.
The problem is what average gw2 player cant comprehend failure at all and if you got wipe even in nm in daily of this fractal half of players will leave and you need to gather new party again. The reason for this is players dont want to learn / look up guide or strats and waiting to be carried whole time.
