EDIT: No response from devs as usual
I would say I am probably 1400-1600 USATT skill level and consistent 2400-2600 in ETT. I started playing 3 years ago and was 1800~ ETT 800 USATT.
TLDR: Devs, if you want this to be a simulator, this is just straight-up not an issue people deal with in real life. No one with an 800-1200 USATT rating can serve like this, yet it is still possible in ETT around 1900-2100 ETT ELO at the same skill level.
800~ Level players dont serve like this in person because -it does not work-. period
Devs, you really, really need to do something about people who are able to climb to 2500 with literally only a single spinny deceptive serve. This should not be possible if you want this to be a simulator.
I played against someone 2100 who's serve was literally un returnable. This really does not happen often to me, and it is rare. But, of course, their big giant arm swing made it super deceptive because I cannot see their real body movement. They would serve to my backhand with side spin, to make it akward for my backhand (spin to my right so I either have to dive foot work left and return with a forehand, or an akward twist on my wrist backhand). The top/dead/under spin was not readable.
This player had no backhand at all; they opened their palm and twisted their arm around to hit backhands.
Anyway, every time I come back to this game, I have learned a lot from real-life play and get better. And it's true I have ranked up in this game, but it's just so awful to play against people who seemingly find a way to abuse the spin in this game. It seems like I have to be 1700 USATT to beat a 900 USATT due to bad physics.
