Uncarbonated mead doesn't need to bottle condition, but it can experience bottle shock.
Wines often have this problem; the flavor takes a strange turn after it is bottled, but then recovers after 2-4 weeks. Meads are basically wines, and often respond like them. So don't be surprised if it has a funny taste during the first month after bottling, but then comes back the the taste it had just before bottling.
And it will continue to get smoother and richer over time. A couple years from now it might turn amazing.
