I know of another way, but it involves you to spend money.

You can get fusion boost armours from Chance Chest Events, where when you open 11 chests at once, you will get 3 fusion boosts, etc.

You can also get one with the Limited Time Only "First time spenders" where you get 3 fusion boosts when you first purchase gems.

These are all limited time offers, but yep.. they want you to spend your cash lol.

other than that, I only know other ways which you've stated above. Hope this helps! ~
