Currently, there is no point to having an upgraded Artemis suit. Shields are never used for biology scanning, and increased oxygen is moot since a ship or SRV is normally nearby. The suit only exists for the tool. The genetic scanner tool, when upgraded, should allow the user to scan multiple different bio forms at a time, as many per rank. Example: I had to fly around a crater ~20 times to find 3 samples of 5 different life forms.. very inefficient! Ideally an upgraded Rank 5 suit should allow me to scan up to 5 different plants at a time, allowing me to make less hops with the ship or SRV and save time and effort. Otherwise, upgrading the Artemis suit is pointless and bio scanning exists as a performance art of getting in and out of a vehicle.
