Position 4 Hanzo or Gakido

The layer of debuff that matters is Poison. You can deal with Ignite.

If they're running Chaos instead of amplified healing, That's better for you.

A simple team that works quite well is Sage Naruto/Bee/Hanzo/Sailor

Doesn't focus on buffs, and has enough self-sustain.

Or better yet.

Roshi/Bee/Hanzo/Sailor

Notice how I'm keeping with Hanzo+Sailor. It hard counters that chaos combo, Either Hanzo will remove it and give your Sailor a standard to remove a layer with her heal. Or your sailor will heal off Hanzo.

That Han team is better with Mei, not Roshi.

Lol you clearly haven't faced this team enough to understand why it's superior to every other team in the game so you're just throwing around your opinion and trying to defend it by pointing out that you have experience against the team but you obviously don't since the first thing you recommended is gakido and hanzo lol like do you actually think OP and like most of the people in here have never tried gaki and/or hanzo against healers!? Anyway in case you really had success against healer teams with gaki/hanzo and you're not talking out of your ass then imma tell you straight up that you won solely thanks to this thing called "BP Differential" because none of them work hello? I hate biased players that recommend something and say it works but then 90% of the time it's just them being stronger than the other person... Now I wanna know how in hell/heaven are han+mei healer teams better than han+roshi healer teams? For example let's put these two in a clean no power differential 1v1 - 1st round both hans use their mysteries which doesn't hurt the roshi+han team at all since this team doesn't rely on buffs (which btw goes for any healer team out there - healer teams do not rely on buffs like barriers/iruka buff/wb asuma buff etc. and if you think they do you dont know what the hell ure talking about), it doesn't hurt the han+mei team too because the enemy han doesn't remove the 40% from the barrier. Then comes round 2 and roshis mystery goes off and the han+mei team now have a useless and squishy mei that no longer has poison or barrier to "provide that extra ump", all she's left with is her 60 chakra mystery that becomes available in the next round and the immobile in her chase and you might think that's ok but compared to the roshi+han team that's just going to outsustain "that extra ump" it's actually going to be the point where you lose the fight. All it takes to make mei irrelevant against han+roshi is to take away her barrier and poison and from there it's a clean fight between who can outsustain the other which obviously is the han+roshi team. You'd know that if you had nearly as much exp fighting people like that as you're trying to showcase, then again the reason why this team is broken is because it is made to outsustain every lineup so no "umps"/buffs/other type of steroids work only hard control/high single target damage and high combos work. Feel enlightened now?
