@failures_not_flattering_is_it Look, I understand your point but you have to realize that this game is pretty casual and since PUGs are thing, having casuals in a random party must be taken into account.
If you want to avoid them altogether, you should make a static (4 and 12) and use the password protection when starting an instance because the very moment you go with a PUG you accept the risks involved so it makes no sense to be angry w/them.
When I was spamming the SP-br training for the campaing prizes, I met several randoms. Some of the runs were decent, some very good, one was pretty bad (underequipped players, one left), but I never left or raged at anyone as it was part of the risk and put more effort on my side.
I completely agree with you on the lack of hard content and I'm not even going to suggest you to "make it for yourself" by joining random parties or soloing 12-man urgent quests because I've tried that first-hand and the lack of decent drops, the bitter taste of effort wasted for nothing, made me hate them.
Which brings to another point: SEGA can make as much as hard content they want, but if it feels unrewarding like the actual content with 0.0000X% drop rates, it's going to become stale soon enough, with casuals alienated and dedicated players frustrated.
Heck, S-Rank Phaleg title gives a phantasm's emblem, solo PD S-Rank title 200 SG, with the latter being a walk in the park.
Ultimates are okish, because you can grind them as much as you want and rng will smile at you eventually.
I also agree with you that it's a shame that challenge mode has been left to die, it was pretty funny, relaxing and enjoyable.
