There has been a fair amount of discussion in the GT Customize Set about the Hybrid Driver, and I just wanted to put down my thoughts about its usage in WBO Tournaments.
1) Trial banning Hybrid until further testing is done. Not even a week after release, an "Infinite Stamina" trick has been found with the Hyrbid Driver, as shown in this video:
https://www.youtube.com/watch?v=WYnJrwLPV5s . Having a Bey spin for 49 minutes (assuming the timer is accurate) is way too long. The Go Weight made the Bey really shaky, which likely messed with the sensors in the Hybrid Driver to the point of having it constantly activated. The test was just a solo spin test, but a Bey that has little recoil can probably take advantage of this exploit. There are probably other ways to mess with the sensors that we don't know of, and therefore cannot combo ban Hyrbid from all of the potential abusers. Even without this exploit, Hybrid is pretty good at Tornado Stalling for longer than Zephyr' and Accel' but immediately goes back to the middle when the motor deactivates.
2) If Hybrid is usable, turn it off. Banning the On mode for Hybrid might be the only way that ensures that it doesn't break the meta. It seems to have decent LAD, but not game-breaking in any stretch of the imagination. The Driver's Shape, OWD, and size make it significantly easier to destabilize than most other Drivers, especially if the motor is turned off.
3) If the Hybrid Driver is usable in On mode, should putting the motor in the wrong direction be legal? If so, it would have to include the right to changing modes once per match. So far, no official source has said anything about needing to be in the correct spin-direction. The correct direction would lead to Tornado Stalling and more Stamina, while the opposite direction would lead to a more aggressive approach. Reverse mode Hybrid would work as a pseudo Ig', which could push for the legality of using the opposite mode, assuming that electric Drivers are allowed in the first place.
