Nothing's changed. Literally the only way to stop an interruption is to use the jutsu out of turn sequence so they can't interrupt you. If it's on auto, the enemy will even waste their interrupt needlessly.

Put important jutsu users at Move 1 so they go before most interrupters.

The waiting game is the only way to make it work. If you have been farming tokens, get Kisame. His autoattack drains chakra and makes it so the enemy doesn't have any to interrupt you with. You can safely use your jutsu after Kisame attacks.
