POSSIBLE SPOILERS

What did they need the blasted radio tower for in the beginning exactly? I was beginning to play the game again and I don't recall why anyone needed that place.

They needed it to broadcast the wordlwide show with Edea and the President i think. remeber? The TV Station at Timber.

If it was insignificant, i would be VERY angry, as ELVORET IS TOO HARD!

Yeah, without it, they couldn't do a live broadcast, and they really wanted that.
