As a water main, I have never ~ever~ had trouble beating a fire main that's the same level or even a level higher than me. First of all, they're pretty squishy if you can combo their main even once, so bye bye all these supposedly "broken" passives. As for the team you keep repeating, the counter is so easy. Literally any semi decent water team can take it down.
Let's take the team I ran from around level 55-70. Hinata, Sasuke, Kisame. First round you cancel my Hinata's mystery. Even if you are fast enough to cancel her (which I don't think I've ever had happen before), I have a counter. After Kisame's done with his standard attack, even if he goes for the Neji (and he won't, he'll go for the fire main) the next standard I'm healing my Hinata. Otherwise, if he goes for the firemain, he's now possibly set off a combo which gets your fire main down to 3/4 health maximum by the first round, even without that combo. If you've got a mirror on your main then now you've reflected some poison onto either Hinata or Kisame, no big deal, after Kisame's done moving, I've just used my heal on either him or Hinata. Sasuke will do his standard and we're on to next round.
Let's say you've put up Gaara's barrier, there goes Sasuke's up right after it. I'm not *, I'm waiting until after Gaara starts that mystery to use Sasuke's. Even if you put Gaara's mystery up first round, with the twenty chakra that Kisame had given me, I can put up Sasuke's at the same time. My Sasuke's always going to interrupt, because he's in last position, and your Gaara's already gone by then. During round 2 I'm using Kisame's mystery, stealing chakra and more than likely killing most if not all of Naruto's clones, even with Gaara's initial shield. If I've stolen enough chakra, off goes my own shark bomb in the same round, immobiling a good portion of your team from the crit I may get or at the very least causing some damage. All this time, I've been layering poison on you with every hit.
By now I'm using Sasuke's Kirin next, setting off a 10 combo on either your fire main if he's not dead, or Neji.
My poison is ignoring the shield on Gaara as well, so he's dying quite slowly.
Once I've killed both the main and then Neji, I'll get rid of Naruto quite quickly. Leaving only Gaara to whittle down.

Let's say I'm not using poison tai, then I'm using the chakra steal, so as I kill Naruto's clone spams every round, I'm getting more health and more chakra, and Kisame's getting health. Both of us are going to most likely tank through everything you throw at us.

And this is just a f2p team. My current team would wreck that team in two rounds. First round, Animal Path goes last, so I'm not using her tag until I know you aren't using Neji on her. Then she tags the whole team, next round I use my water bomb to kill the clones, gain chakra and immobile the targets. Then with that extra chakra in the same round I use Konan to hit the whole team. Anyone can beat that team as long as they're not * and assume that you're going to try and cancel them and save their heals for opportune times and make sure they're not using vital skills when Neji has an interrupt.

Okay dra, first of all, you absolutely NEVER mentioned you're using GNW Gaara (which where exactly do you intend to get him), a 9 tails Naruto (also not f2p), and GNW Neji (which you act like is a god, when I can easily take him down second turn). On top of all that, you've got my formation wrong to boot.
And to add to that, I'm not an idiot, you're not cancelling my animal path, because I'm not using her until the very end of the first round. And even if you've used Neji on her, the next second I'm using my heal on her as well, clearing that debuff.
But since we're playing dream team scenario, let's say my Sailor Sakura is fully upgraded along with my Gakido. You're not putting any debuffs on me, and if you are it's because I've done something *.
