True but that dosen't mean that they are intentionally letng Obito to attack them ..Avinash, he didn't want to avoid Juubito's attack; Tobirama and Hiruzen were testing Juubito's abilities by using their own bodies. Sasuke himself stated it.You must be registered for see links
Tobirama tagged Juubito 5 times and you honestly believe he couldn't dodge that attack?
He tagged Obito 5 times and do u think Tobirama Used those tags on Obito in a sequential manner(One after another)...?
He can use multiple tags at a time...
The fact that Mianto surprised that much proves that Obito is out of thire league..
Tobirama can't dodge that attack not even Minato if u ask me...
