Hey there,
While I understand the concern, the problem really doesn't lie with Tenten.
The team she is useful in is just pretty strong for a cheap team, but it is at the same time easily manageable with high damage outputs.
To show it on an example, my Iruka creates 3k shields. Opponent Tenten around my power level barely breaks them, if at all. Damage may be big, but it won't create any additional effects like combo chain. Many ninjas now have debuff immunity, and one of most safe ways to play is to run a debuff clear on the team.
Since today we got Han, so I suppose buff removal should help a bit ;p
