The dead ringer, because you can't cloak yourself anyway equipping it, is supposed to get you out of the way of pyros, so they think you're dead. Of course pyros kinda defeat its purpose since they will just flame all around your body.
And Cloak and Dagger is actually probably the best. I can't see how you hate it. Almost 95% of the time before the update I was always in need of some sort of recharge, but I couldn't get a recharge without the enemy noticing or having to uncloak and get myself killed.
