Argonians did not receive a bonus to the restoration skill until Skyrim and it was only +5(Imperial is +10). The one thing Argonians have ALWAYS been the best at is movement speed. Ironically the slowest race (orc) got a bonus to sprint speed instead of Argonians. In the games that had Athletics and speed, Argonians have always had the highest combination of the two.

Argonians have also historically across the games had low starting hp due to having low endurance, so its a bit strange that they get a racial that gives 1000hp. Potion racial is obviously complete non sense and doesn't even require an explanation. Only racials that they got right for Argonians was swim speed and poison/disease resistance. Everything else is a complete fabrication with no justification.

A lore and game accurate racials for Argonians would be something more like

1: 15% extra xp in the Ledgermain skill(Argonians are the greatest lock pickers in tamriel)
12% movement speed increase water and land

2: 1910 max magicka and stamina(argonians have never favored one over the other)

3: Immunity to poison status effect(argonians are not immune to disease, but have been immune to poison)
2310 resistance to poison and disease
When you take damage you heal for X hp over X seconds(hist skin)

4: increase weapon/spell damage by up to X based on missing health of target(I think this would be unique and also would fit the shadowscale/assassin lore)
