Yes most of the people I play with have a good enough connection that you can anti air on reaction, but the timing is much more strict than offline. I never play ranked or randoms but I was just saying that in defense of the OP (who may be new to tym and used to playing ranked/randoms) that it can be very difficult to anti air in certain internet connections. If you stick to people you know and that you know have a decent connection I agree with you it is fine.
