What about a team something like this?

Dragulia90

Old Ben (lead)
B2
Sun Fac
RG
5s


Could this have a chance?

For running down the timer yes, I'd hate to see all that in a barris lead

You are talking about arena squad? Bad idea, 100%

Arkham

No damage dealers.

Sideropenik

Very strong evasive and taunting team. B2 dispells all positive effects on enemies, Sun Fac does so on his basic on single target and he taunts a lot + he recovers a lot of hp, Fives counters and slow downs, RG taunts whenever someone is under 50% of health and Ben grants evasion and debuffs. Really nice. Try to this team and mod Ben properly with speed + potency, he doesn't care that much about hp, because everyone in this team has a lot of them. Be careful for DPS team with stunners/dispellers. If someone stun 5s and remove taunts, you lost your advantages and have no real healer for the team. Consider using critical avoidance and be careful for teams modded with accuracy. Also watch out for assisting squads. Also increase your dmg as much as you can.
Good luck

Try palp instead of old Ben and replace b2 with ST.

Supercat

I was thinking add palp as lead and replace 5s with shore. Then you have tanks and damage.
