People just need to assess their party's strength and weakness and adjust your strategy accordingly. Just like the pre-nerf'ed CoP. There's no single winning strategy that will work for everyone/every party. You really need to look at the various strategies out there and adopt them to what the players you have in your party (not just for job but the strength and weakness of each of your actual players).

I won with: SMN (PD to start), 1x MNK, 1x PUP, 1x NIN, 1x RDM, 1x WHM. Used 2 items (2nd by accident). We have 1 Emp (NIN) and no other one has Emp/Relic/Mythic. It can be done if you plan accordingly and adj based on what you have. For example, our RDM originally was going to be a BLM but skill wasn't capped so we switched to RDM as backup healer/lighter-nuker (chance of need for chainspell nuke). WHM was originally going to be 2nd MNK but PUP's WHM wan't geared/skilled. So we adjust there. NIN originally was to be PLD but we rather have more damage since we already have PD to start along with items. Only MNK die after PD wore off. WHM there to cure bomb after PD and RDM there to add dmg with Nukes and Debuf and backup heal. PUP's pet was setup as BLM nuker. SMN used Garuda and PClaw whenever it's up (~1k per BP). [note: Wind Blade was only doing ~300 dmg though and 5/5 on merit on Wind Blade but do not remember what the day was].

Good Luck everyone!
