Ill start by answering your question- VSM (minus REO) was at Winter brawl (Jr, Maxter, Claude got 9th, Revolver got 5th?) So it wasnt really a bad showing.
Now back to what else you are saying. Dude, you are jumping to hella conclusions based off of unrelated things. 2013 is young for MK in general cause weve had 3 majors. SCR which is west coast insanely far from NY and which GGA also didnt attend minus Bit. Winter Brawl which only some of VSM was at and where they didnt do as well as normal but didnt do bad by any means. Then you have Final Round, where some of GGA was and they did really well. No VSM was there and even the known hardest hitters of GGA (dizzy and bit) were not there. So going by the last major where almost all of VSM and GGA were (minus dizzy i think) was NEC. GGA had only bit getting 5th and maybe some others making top 16. VSM made up the top 3. REO won all the mlgs before that as well with maxter and Jr always on his tail. We have to wait til something like EVO, the fall classic, or other fully stacked tournaments to really talk about this changing of the guard. I dont doubt that GGA is probly the frontrunner right beside VSM with all other scenes not really challenging either, but you cant say VSM isnt still the best as well.
