You two are talking two different things. You are saying you are curious to see what elements will remain, since the original list will stay the same, always. Basically, your list is "list of elements still in the game", while fippe's is "list of elements picked at the start."
Regardless, the "list of elements people chose" won't change at round 3, since the element was still chosen - people got eliminated, but the choice was there.
I'm pretty sure Fippe should have understood that, though..
Exemplifying, we have four hypothetical members A, B, C, and D.
At the start, A picked
, B got
, C got
and D got
Here, you can see gravity was picked twice, and the list of elements picked at the start stands as Entropy, Death, Earth, Life, Fire, Water, Light, Air, Time, Darkness : 1 ; Gravity : 2.
However, if player B gets eliminated first round, the list of elements REMAINING in game will have narrowed down to Entropy, Death, GRAVITY, fire, water, light, air, time, and darkness, only one of each.
Even then, the list of elements CHOSEN remains as the list that was at the beginning of round 1; player B just did not survive.
