1) Your team gets owned by blitz mb teams and root mb teams of every kind, the only reason you don't meet them anymore as often as they used to be there is exactly because that han team is there in arena. during next months you'll began to see a ton more samui, darui, ay, mb teams with people that will begin to be aware about how to use it efficiently and while you will lose against them with quite high chances that han roshi sakura team will continue to stand a chance against it.

2) Do you think all those azure fang users are all idiots and go there in arena with it just because they think is good when is not? Couldn't be that maybe you own one of the very very few teams that actually beat it? No, eh, this kind of thought never came to your mind.

3) Are you aware you are using an ultra p2w ninja? Make a comparison with teams that use them too and look at how many times you can win in arena agaist them. Can your team beat hokage tsunade triple healing team with roshi or 6 tails naruto? No, Can your team beat itachi susanoo, masked man, sb, onoki/mei team? No, can that team beat hashirama full skillbroken, six tails naruto, earth main, kushina/gakido/bee sst? No. So what's the point in making a comparison with a f2p team?
