Depends, if you play at a level or on a surface that allows a decent bouncer then that's fine as it s a delivery a batsman is likely to come up againstIf you are unlikely to ever come up against anyone who is gonna get it up high enough, whether that's because of pace or the wickets you play on then there's no pointWhy face bouncers all winter nets in hard indoor surfaces then come April and nothing gets above hip high.
As a batsmen you shouldn't have any issue with what a bowler is putting down. You should be good enough to be prepared to face anything, smash a couple out of sight and they'll know where to bowl it.
