I guess a lot of people are most likely to be getting Loopin Supers after they have drained.
For the simple reason that if you are in a mb or a ladder mode you can reach the 60 ghosts required, but can’t go past that. This leaves 3 options either, you complete the mode ‘properly’ with the ball still in play and then have Loopin Supers thrust upon you, or you drain down to 1 ball from mb and again have the Loopin Supers as the only option. These 2 options are still fine as your SJ value can be high and with playfield multipliers I’ve had a score of over 1bil from it.
However, if you drain while on 60 ghosts, your new ball leaves you with only Loopin Supers to shoot, but with only the default JP score of 5mil (iirc) - at this point it’s all about starting Loopin Supers and then waiting for the timer to expire so you can move on with the game.
Personally, I like it as it stands. There’s a decent reward for playing Loopin Supers after you’ve played a ball for a decent amount of time, which you lose if you play it at the start of a ball.
