well you can try using Ninja and Rathalos for a solid dps combo or run Michinaki as well. . They both pump out a ton of dage as duel dps. then you can run Freya, Duchess and another support(skullcrusher) ... can mix and match with supports but nina and michinaki really escalate damage since michinaki can join in an attack. michinaki works well as a dps option because of his passive. can work well mith Mithrala as well since she puts out Hex and she poisons.
You dont have an unkillable setup but you can do decent damage on killable runs.
sadly no wixwell but you have an amazing decent roster that can 1-2key UNM once you get Mikage im sure
Honestly the team seems fine to me. Of course you need to make sure things are properly tuned - especially because you have Ninja with Skullcrusher. But, assuming you're getting your standard 1:1 rotation without buffs falling off etc, the only thing I'd want to do is swap Ghrush for someone more useful damage-wise, eventually - of course while maintaining the Leech debuff.
Suffice it to say everyone needs WM/GS, but otherwise your setup looks solid. Yes, you could drop Freyja, but honestly, finding someone else with both Block Debuffs AND DEF up is pretty challenging.
In terms of inconsistency, I wouldn't be surprised if red affinity was your biggest problem. If Ghrush gets his Leech resisted/weakhit, you're in trouble. Make sure his A2 and A3 are disabled.
this dude in our clan is using scyl as his healer, Ycesna for dec atk, def def, weaken and some healing, mithrala, Rathalos and geo. manages to one key. im sure you can come up with something
Ycesna can be replaced with Lydia.
Very much worth noting that Yncensa's a1 has whoever has the most cdam team up with their a1
Deacon is a very solid choice, with the A3 turned off. Dazdurk is pretty good too (also with A3 off), since he's void. Dazdurk A2 can also make speed tuning a bit easier since the TM boost can be factored in to lower overall speeds potentially. Just make sure you include it in your rotations on the calc and pay attention to not mess up the rotations.
