Large scale mass effect fields are bad:That's... wouldn't that make it trivially easy to land even the largest ships on a planet? That seems to contradict the lore.
Lowering the mass of large ships enough to land under gravity will result in spewing deadly radiation everywhere. Yes this does cause some issues with Soverign, and the other Reapers, landing but there are explanations there. Given the Kodiak exists I think the simply explanation is that with enough Eezo you can generate a tight field such that your armor is outside the field and thus acts as a radiation barrier.ME Codex - FTL Drive: Appearance said:To an outside observer, a ship within a mass effect drive envelope appears blue-shifted. If within a field that allows travel at twice the speed of light, any radiation it emits has twice the energy as normal. If the ship is in a field of about 200 times light speed, it radiates visible light as x-rays and gamma rays, and the infrared heat from the hull is blue-shifted up into the visible spectrum or higher.
