concerns on the usage of DZVP
...
We do not know how well DZVP
...
performs for charged molecules, and for properties other than conformational energies.
DZVP results are less accurate than literature for medium/large systems largely due to lack of DZVP-specific dispersion parameters and three-body term
...
.
The need of inclusion of diffuse function: diffuse functions are for describing anions or dipole moments and for accurate modeling of intra- and inter-molecular bonding.

Questions
other functionals/ basis sets to test?
wB97X-D3
Is MP2/heavy-aug-cc-pVTZ reasonable for reference? (too expensive?)
