Thank you Harmonix for listening to us and restoring the integrity of the game and its leaderboards.
I will probably continue to take a break from Blitz due to being completely burned out by excessive pinballing, but I at least know that the game I come back to will have legitimate competition again. I could not take the game seriously knowing that some of my scores and the scores of my competition were literally unbeatable. It also didn't help that the only effective strategy in a music-based game involved ignoring the music. With the return of flame notes, those who actually play the song may have a fighting chance once again.
The only things that could reasonably be done to further improve the balance of Blitz are buffing Runaway Notes and Shockwave. Those two powerups remain useless for high scores, but it won't necessarily be the end of the world if they don't get buffed. They just won't ever be used by top players in any competitive situation outside of locked powerup competitions.
If I do come back to Blitz, I'll probably just play it for fun and get whatever high scores I can. I don't think I'll do much more pinballing though, because that just killed my enjoyment of the game entirely.
