I doubt you'll see the behaviour changed. At best, you might get them to change the wording of the power.
In part, ME Hulk's Grand Entrance was intended as a counter for Rocket & Groot. If an enemy Hulk's Grand Entrance activated during the player's turn, then you'd have a cascade whose damage is beefed up by the player's strike tiles. They might lose some of their strike tiles, but there's a potential to do a lot of free damage to the enemy team before even making a move.
The only way to move it forward and keep it fair would be to code in a new mode where one player's powers can manipulate the board during the other player's turn and also accrue AP/damage from the board settling. I don't see that happening unless they decide it is critical for a power of some new character they've dreamed up.
