Don't forget i mentioned the Climate in High Rock being a lot colder than the Bosmer/Khajiit are used to (as they live in tropical climate), so a direct naval supply line would have to be established for the long term invasion to work, this is risky as those waters have lots of pirates.

The Dominion can invade Cyrodiil by land they don't need to use the Tompac Bay(i may have spelled it wrong) Or alternitively they can start the attack from Anvil, western Cyrodiil.(this risks the Redguards attacking though).
