Of course you should be challenging medium.

You will be shorting yourself of higher tier rewards. If you have enough level 70-80 ships available for a given map, you should even be challenging yourself with hard mode. I'd say an average of 55 should be enough for a medium map.

CVLs: level your weaker CVLs so it can handle ship lock on medium.

DD: K2 Ayanami to have two high luck destroyers.

If you have time, and want to challenge more maps in hard mode,

CL: Level one to level 70.

CAV: Level one to level 70.
