@Zeke Honestly it's more about skill and class than it's about gear, within reason of course. Klauz weapon isn't exactly hard to come by and there's always the option to swap to a different one. Most S-Augments are pretty affordable, especially since 4man TPD is very generous with them. You don't NEED the best in slot meta affixes on units, there's plenty of cheaper alternatives which are strong enough. You usually just end up trading defense and or are limited a single attack type. Lower defense can be overcome by well, playing better.
You also gotta keep in mind that you can always build a premade party to have Te buffs for 3 people(one person buffs and then changes class), Weak Bullet and someone applying Jellen for Phrase Decay. This already helps with the DPS requirements greatly. If you can beat, or at least come close to beating Depth 100 you will meet the DPS requirements for the EQ. D100 has 250m HP with a time limit of 15min, 4man has 1050m HP with a time limit of 22min( ~20min if you subtract downtime & cutscenes).
As mentioned before, it's mostly about knowing your class and becoming comfortable with the EQ. Stronger people in party can as well make up for lack of DPS from weaker players(gear wise). There is UQ Sodum which lets you practice majority of the UQ whenever you want, only leaving the unique phase which you need to learn "the hard way".
It's not an easy UQ, it's not meant to be one and hopefully stays as such. Camos will tank in prices within a week or two. Camos on JP went from costing you hundreds of millions or sometimes over a billion into a 500k-25m range in a span of ~2 weeks.
