If you contagion a miasma 2 it will add an extra 50 potency, for a total of 120 so yes, its more powerful than a ruin 2 but only if it's allowed to tic for at least 24 of its boosted 30 second duration. We are however talking about during DWT so that won't be as powerful as a 200 potency ruin 3 which you should be using during trance anyway.

The only time miasma 2 will have more potency is against 3 targets and again is allowed to tick for 15 seconds. Remember contagion can only hit one target and the boosted miasma 2 can't be spread by bane, so one target will take 120 potency, the other two will take the regular 70. I can't think of a situation that you will be attacking multiple targets that stay alive for that long.
