I do like the idea of qualy with race fuel but it really wont change much unless overtaking is fixed which i imagine frank is all over at teh moment on not far from it
I liked the possibility to have a light car on the start of the grid, that opened some more strategies. as it is these days most tracks need 2 stop, one or two can be done with a one stop. 3 stops only work when you have a superfast car/driver combination and make "the vettel" (when rb was superfast)
I also would love to have a qualifying session that last one hour and is 48 hours after qualifying starts. the manager enters the settings for the stint/s and when the session starts it is up to the drivers
