I haven't tested this but will say
I'm not a fan of anything that makes rallies longer...when people run out of accelerations the rallies are simply boring. If it's harder to finish points in realistic mode then it's a big no
Also net play should not be easier, it is annoying for the player on the baseline to try to hopelessly pass the net player when they are in good position at net and also those rallies(other player at net, other back) are mostly quite unrealisitic. On fair mode net play is presently quite hard and mostly possible when you construct a point well with accelerations and get a weak return, like in real life. So no thx to easy rushes to net
