Actually he was conceding that the person maybe had a point in regards to elemental with heavy implications of it being irrelevant. The English language can indeed be very precise when used precisely, but it can be very nebulous if used in the way GC used it. So no there is not only one way to interpret his tweet.
"Do players really silence / interrupt Enhance often? Elemental... maybe."
It is pretty easy to take this statement and run with the logic that his question was rhetorical, and that he doesn't see it being an issue for either. His statement can easily be read as (Do players really silence / interrupt Enhance often? No, I don't think they do. As for Elemental you maybe have a point, but it’s not really an issue if you ask me.) Of course this being twitter and people using rapid fire thoughts makes it hard to really know what he was saying due to the stupidity that is twitter.
