[Dormammu power generation when taking damage]

if dormammu is damaged by an attack that does not grant power to the defender equal to the damage suffered (like wasp buider when she is tiny) ,does he get 1 power?

[Activation token and reactive super powers.]

By rulebook the activated token is placed on a model after he completes his second action.

What happens if my model get dazed by a reactive super power that trigger after the attack is resolved , do i get the activated token? 

And if it doesn't get the activated token and i immediatly field dress the model, what can he do? He can take 2 action? He just do his remaining actions (if available)? If he doesn't have any more action available he get an activated token?

Thanks

[A couple of question on squad building and affiliations]

It is possible to lose the affiliation during a game if my models remaining on the board of the declared affiliation are no longer more than the 50% of the team? And what happens to my affiliation tactic card?

When exactly is declared what affiliation i`m playing? If i ,for exemple, bring a team composed by Black panther, okoye, taskmaster, captain america ,iron man i could play both affiliation.
It is declared after you deploy (like when you have multiple leaders for the same affiliation) or when you reveal the squad?

Thanks
