I'm going to spend 1500000 in Ally Points.

Don't spend them the devs said they would likely be useful for something else later on.

No, entirely the opposite.
From the dev post when they stopped tournaments:
"Ally Points were made much more plentiful to make participating in Tournaments easier for everyone. Now that Tournaments are being paused, you can choose to spend them on Bronziums or hold off in the event they get used for a different purpose down the road. At this point we have no plans to do so, but in the coming months that may change."
