Problem being we've never seen this "V2" bullshit anywhere else. We only saw it when he was trying to stop Naruto.
The notion that Raikage was holding back and staying in his V1 mode while fighting sasuke is already hard to grasp. (HE LOST HIS GOD DAMN ARM IN THAT FIGHT, WHAT OTHER TYPE OF MOTIVATION DO YOU NEED TO MAX OUT?)
Now you guys would have me believe he was also holding back against MADARA????
The same dude that is currently beating Hashimara and is threatening to destroy the entire ninja world???
There is NO v1/v2, there is NO "MAXED OUT" whatever bullshit. This mythical V2 thing was only aesthetics used for that panel for visual sake.
