I'm thinking the fitter is not very good, if he didn't actually see you on the bike before or after you requested the adjustment.
The only reason not to tilt the nose too high is that it would cause discomfort.
Did you have a fitting when you bought the bike?
- Gray 2010 carbon WSD road bike, Rivet Independence saddle
- Red hardtail 26" aluminum mountain bike, Bontrager Evoke WSD saddle
- Royal blue 2018 aluminum gravel bike, Rivet Pearl saddle
Gone but not forgotten:
- Silver 2003 aluminum road bike
- Two awesome worn out Juliana saddles
