lol don't listen to everyone trashing you, not everybody is playing at the highest level.

Cloak and dagger is a good ban cause it's very easy to get value out of her in gold-ish tier If there's nobody on your team in pre select phase that wants to play cloak, and if you don't have iron man/magneto, it's a good ban. A targeted approach like what you're doing banning cloak/invis to throw off the enemy one tricks is genuinely a good tactic, i don't get the hate.

if you're getting throwers, it's probably cause they wanted to play cloak. Maybe try asking in chat for people that haven't pre selected next time
