yeah, synchro arc's animation was shit mostly. Too bad they never got to remake nirvana high paladin's summoning animation in 3d like they were able with ultimate falcon.
But the animation was the main thing i hated in arc-v. Imagine if yuya was always drawn like in this scene "https://www.youtube.com/watch?v=sM5ZQ5_-gkU". He would've been taken a lot more serious instead of the kid-like animation like in here "https://www.youtube.com/watch?v=NG-iJV56NWk"
