It doesn't matter that you can get 30 million on a one lane song.
ANYONE could do it.
Easiest use of flame notes that any casual player could try would be any 2 lane song, (Redemption Song, Rodrigo y Gabriella songs, Landslide, ect.) You won't hit anywhere NEAR the top. Ever again.
And you can't change rules like shifting to play 2 lanes, or the way flame notes spawn without destroying the ability to hit the top scores already on leaderboards. You can't do it.
Only thing HMX should be allowed to do it BUFF numbers and behaviors of non high scoring powerups. Even STILL though, bandmate/flame SHOULD always be ruling out on top. Why? Because it takes the most amount of work/skill. You can't have a set of powerups that takes a ton of reflex skill and management and then have it equal out to a score that just blast notes highways with road rage. It makes no damn sense.
Harmonix is scared to separate the men from the boys and yet with power ups like jackpot/2x co-existing you see that was their original intent all along. So HMX clearly doesn't know what they want.
As for the tournament, hey that's cool. I'm sure you knew about this way ahead of time. I'm also sure you knew what was scoring high on leaderboards...WAY ahead of time as well. So why punish everyone because you procrastinated in balancing your own game?
Like others have said; so now that flame notes are literally worthless and fall into the category of runaway notes and even 2x. You have essentially taken one more power-up off the table of usefulness. All scores from now on are probably going to have used blast notes. Then are you going to nerf that next?
Clearly the people who tested this game were not at the level as many of the concerned players in this topic. Get us all in a room and we'll balance your game game out.
