i'll give you bosmer and orcs being useless, glad we could agree about something. but the argonians could have done the exact same thing at the hight of dunmer power, they were provoked by a thalmor agent and only then did they launch an attack, arognians are docile despite our unrivaled abilities
Unrivalled at what, precisely?
Breathing underwater?
The Dunmer have spells for that.
Using spears? The Dunmer can do that too (unlike Imperials and Nords, apparently).
Assassins? The Morag Tong was always stronger than the Dark Brotherhood.
Magic? The oldest wizard in all Tamriel is a Dunmer, in case you forgot. No Argonian will ever be half the mage a Dunmer can be.
Swamps? Heck, we had the Bitter Coast until Red Mountain presumably incinerated it. Hardly an achievement either way.
Argonians really aren't good for much of anything besides manual labour.
