The probability weight is the proc rate, or 1/12. The expected number of procs with your 12 rolls is going to be the sum from 1 to 12 of 1/12, or 1. We are in agreement here.
But we're not just interested in the expected number of procs, we're interested in the expected damage dealt.

Agreed!

There's an identity, that for a linear function of x, the expected value of the function is the function of the expected value of X:
E[aX] = a * E[X]
This is the calculation you are doing. E[d(x)] = d(E[x]). However, the expected damage is a function of time, and it is also a function of whether or not there has been a prior proc.
Therefore, the linearity of expectation does not hold, and it is neccessary to calculate the sum over all the possible outcomes.
This is why you cannot simply multiply the damage by the average time for a proc to hit.

This is where you are incorrect. You get 1 proc per fight on a 2 minute fight in the specific example I gave. On average that means you will get a proc halfway through the fight. That is an average of 9-10 ticks plus the DD. If you proc the weapon again during that time, you just get another DD proc (more damage), and the DoT continues to tick damage normally, as if the second proc never occured.
If the DoT is doing an average of 9-10 ticks, that is 10 x 24 (Damage per tick) + 40 (Direct Damage) = ~2.1 DPS per fight on average. This is not taking into account white damage, and the proc rate is actually 0.65, which means you are probably getting another tick or two on average.
Remember we are looking the the average over all possible fights, not an individual fight where you could get 0 procs, 10 procs, etc. Your average procs per minute is still 0.65.
