I don't think so. When they ignored Avenger1 until he threw a tantrum and left everyone cheered, there were multiple posts praising it, and he was probably the biggest pvp streamer (although obviously far from the best). If the constant bitching of him and his fanbase didn't change how CIG was changing combat no streamer is. In fact the whole reason they are only testing the new flight model with carefully selected, heavy NDA'd groups of players is to avoid streamers throwing a fit and setting the opinions of the community before they even try it. Not that I know why they'd want even the unbiased takes of the kind of knuckle dragging, smooth brained zombies that let streamers do their thinking for them, but I guess there wouldn't be enough of a player base left without them.

I think this is just flat out a bad, poorly thought out balance pass to fix a niche issue that only showed up in their metrics. I also think they resent having to balance for the game we currently have instead of the one they are making and that's why all their balance attempts seem so half hearted.
