I looked at the screenshot you posted.
It shows the gear of your Drexstar.
It shows the gear of your Deacon.
I can't see all the gear on your other heroes, but I assume your issue is gear related.
I think you are not building your heroes with the right stats to function properly.
- You want every hero to have 200 ACC for NM CB.
- You want every hero to have 4k DEF for NM CB.
- You want every hero to have SPD's between 171 to 189 for NM CB.
- You want every hero to have Lifesteal gear on your team, unless you decide to add healer to your team.
How close are you to the above things if I may be so bold to ask?
Now here is another thing to think about.
Clan Boss has a Flex Spot.
Let me give you a sample team:
Lets say you owned Rhazin + made a CB team with what you have.
The set up might look like below:
1st hero - Sepulcer ----------> ATK Down + Block Debuff Buff + Increase DEF
2nd hero - Rhazin -----------> DEF Down + Weaken
3rd hero - Frozen Banshee --> Poison Sen. + Poison
4th hero - Skullcrusher -------> Counter Attack + Ally Protection
At this point, All the Debuffs you want on the Boss are being done.
You are doing the above Debuffs with 3 heroes (Sepulcher, Rhazin, & FB)
The 4th hero in the team (Skullcrusher) is helping improve the consistency of the team.
I will explain how he improves the consistency below:
Most of your Debuff heroes are doing there Debuff on A1 Move.
Skullcrusher Counter Attack enables them to keep using the A1 move.
This allows them to have steady flow of debuffs.
Now that I have explained all the above, You can see the 5th Spot would be Flex Spot
It is a slot you can use to bring in a hero to help you.
---------------------------------------------------------
Lets say you can't get every hero in Lifesteal gear.
What you can do is add 5th hero who can help heal your team.
Some people use the Daily Login Hero Ghrush the Mangler.
Ghrush does Leech Debuff on A1 to help your team heal.
-------------------------------------------------------
Lets say the problem you have isn't Lifesteal gear.
Lets say the trouble you have is getting enough ACC.
Lets say you have all the Lifesteal gear in the world, but it doesnt have ACC in Substats.
What you can do is add a hero like Drexstar as the Clan Boss Leader.
Drexstar has a 70 ACC Aura.
You need 200 ACC for NM.
You make all your heros with 130 ACC .
You add Drexstar 70 ACC as Aura Lead
Bam - you push your team to 200 ACC.
-------------------------------------------------------
Lets say the problem you have isn't Lifesteal.
Lets say the problem you have isn't ACC.
Lets say the problem you have is reaching 4k DEF.
What you can do is add Iron Brago becuase his passive will add DEF to the team.
Iron Brago can give you the extra defense your missing.
---------------------------------------------------
Just to give you a metaphor.
You go to school with a Pencil + Calculator, but you forgot a piece of Paper.
We can slide you a Paper.
We can fix 1 problem.
But if you go to school with No Pencil + No Calculator + No Paper.
You might as well just go home because we can't solve everything.
You got to meet us half way here.
See if you can solve the gear requirement issues with out the flex spot.
The team can adjust.
