I am firmly of the opinion that the best thing to do is just wait. The list variety is significantly greater than it was even a month ago, and as people have more time to refine lists and strategies it will continue to expand.
Yeah, we have plenty more weeks to wait and see how the overall meta ends up unfolding. I think trying to directly nerf turrets before addressing MoV would be a huge mistake, because it doesn't fix the underlying issue. Unless and until the scoring system is changed though, Point Fortresses are going to remain the New Normal. I think we are well past the point of "wait and see".
I agree that nothing should be done right now. I also don't think turrets need a nerf. Non-tournament games are just fine with them. I see the problem as the scoring system that favors Point Fortresses. I'm sure we will see some more variety in the winner's circle by the end of Regionals, but I am thinking it won't be that many. I think Regionals will be dominated by the Point Fortress builds. I think after Regionals are done and we see how truly lop-sided it is will be a great indicator that something should be done.
