5th Panzer Default deck is odd?

I'm new and still getting used to things so it could be me but is the 5th Panzer default deck strange?

The artillery choices seem odd.

No mortars for to support the infantry? No HMG in the Inf after the last patch?

The Flak 20 is the AA (and not great; if anyone has tips on how to make this thing good let me know) for the deck but you have the Gepard just sitting there that seems better in every way but price.

I know it's a Tank deck (and I love their tanks) but the default set up for the division strikes me as one that needs to be looked at.

(And yes I know I can make my own but this is a default, and most people would use it instead of adjusting)
