I agree with Mike, this rule should not be changed after some events have already played using it. They could drop it for Atlanta if they wanted, but probably wouldn't. I suspect this one will be top of the hit list at IRI.
But NOBODY knows how <G14> works, especially in elims. A very respected and knowledgeable colleague of Mike and I, also working at the event, came up to me and asked about it. His exact words, "I'm just asking, because I don't know." My wife who was a queuer was told by one of the kids that his mom said it didn't apply in finals - well, there's a good source of info for you.
We had > TRIPLE scores in QF 1-1 and QF 4-1 at Traverse City. When the <G14> was applied to their next matches, that left the alliance with zero super cells and two practically useless empty cells. When the guy at the outpost exhausted all his ammo in auto, he had nothing left to do but lean back in that comfy chair and watch the rest of the match.
In both cases, the alliances advanced to the SF anyway. One of them carried a > Double Score <G14> into the first SF match.
