Regarding Triosphere...
I've been sent them a number of times..
My Fortress placed at 7 in a 12-1 Ranker in my 3rd roulette
My Fortress was sent by the same person (K-Lox) in my EP roulette and got an 8.5.
Worlds Apart was sent in my EP roulette (J-Boy) and got an 8.0.
The Sentinal was sent (by Evermind) in my EP roulette and got an 8.0
The Hearts Dominion was sent on the same EP and got an 8.5
In standard scoring, Human Condition would've gotten an 8.0 most likely.
I liked it, but sometimes the stacker pushes good songs down, and as in the Recess Round, it can push weaker songs up.
