I think we need a FTL hate-thread.
@Alistair_Findlay already has a video up about this.
Here is what happened to me tonight :
I was roughly on par with the Any% WR time, even maybe a few seconds faster (I finished Candela City 9 seconds earlier, then did Gran Paradiso rather than Green Valley so it's hard to compare), then FTL happened. I didn't race carelessly : I applied the "try to get a lot of nitro at the beginning to use when you're caked" technique.
But... Just watch it yourself. There are two races. Each make me hate the FTL mode. Having to follow-the-leader means that if you're skilled enough to go faster than the leader (and skilled STK players go A LOT faster) you're harmstrung. You can't use your skill to gain time, and when all karts are packed close, you can't avoid any bad item.
In this try, yes. In the previous (yeah, I also failed another attempt before because of this), I had done two other races before.
Any% is quite short, so it's less annoying than when it happens later in a full-game run, but still broken.
More FTL-hate, just look at this (it'll open at the beginning of the FTL) :
I won the race, but I could as well have lost considering how it went.
