Tacticly wise , having megasized veicles goes agace the codex astrates
Spacemarines (and gray knights too) are a mobile , rapid deploy force , Brigning in super heavys quicly is well , i just dont see how it coud be done .
nearly all SM veicles fit in Tunderhawks , eaven the mighty landraider is dockt snugly behind the tunderhawks main cargohold .
Things i would like to do with a landraider.
Mounte a Demolisher cannon in front , turning the landraider in to a truly devastating weapon.
Turn a Landraider in to an adept mechanicus mobile repaire veicle .
Building an improuvd front ramp alowing troops to deploy uphill
