Much of the local scene here has quit or will only seldomly play casuals for INJ before Scorp was out due to the issues I bring up there. I don't feel like it is an invalid argument.
I know how much people love to pump up the MK Illuminati as the best INJ players, but I play against one of the best FG players
GGA Slips, who has proven he is one of the best at INJ too getting 4th at a major with a "mid tier char", who now uses Scorp. I would hope that amounts to some validity being added to my opinion.
For your last point, I don't feel like Scorp isn't doing anything that strays from the "way the game is meant to be played". Sadly, the game does reward alot of the more "stupid" things Scorp does as thats just how the game is. For all we know, he could be one of the factors for why down blocks both ways being used. It was could have been added as the way to deal with things like this.
But, we are not the NRS Design team and cannot comment on how the game should be played, all I know for sure is the game will without a doubt be patched and it will be to suit how they design team things the game should be playing. If Scorp is the engine rapist that the Four Horsemen of Zoning claim him to be, then he will be addressed in a patch.
