Ok first of let me start out by saying by failures I do not mean a complete failure like people using all their moon atomizers and getting a C-Rank. I am talking about when multiple objectives are failed in just about every other way in this UQ.
It's annoying that a big issue I see in this UQ (much like in the Defense Ops and Buster Quest UQs in the past) is people not trying nearly hard enough considering how easy it can be to mess up getting even an A Rank, nevermind an S Rank. Like I don't mean you have to be a tryhard, but I keep seeing people that get hit by every single attack, no one buffing anyone with shifta even though there's multiple classes that can use techs (deband honestly doesn't really do much at the high difficulty levels unless you're a techter, or simply use it because you're a bouncer, so I could see not casting that maybe), etc.
Most people I've seen in this UQ (including me) do not have skydance support, so yes having the people that can cast techs use shifta, is still very much important. Usually even when there's not a phantom, force, techter or bouncer, there is at least a hero, so even then there should still be someone casting it, as hero can use techs.
The time I played this that annoyed me most however is when there was a techter, that didn't cast shifta during the battle with Exegul and that other boss, when the effect wore off for everyone before even reaching that room. They didn't even use the heavy hammer Photon Art for wands, and had a phantom sub (so I assume they should have the tech pp cost and cast speed reduction skill that reduces tech damage), so I don't really know what else the techter was doing most of the battle, as without that photon art the most damage you could do to those enemies is basically a tickle.
Anyway sorry to go into ranting territory, but I just wish people would try harder considering how easy it already is to mess up this UQ. I don't really get why people aren't trying considering that fact, but wish they would put more effort into this UQ than they do. I notice the further into the UQ the players get the less and less effort they seem to put into it for some reason. I'll see them absolutely destroy the first few enemies then take forever to kill even one after that. People should really try more in this particular UQ than they do.
