The Infinite Victim/Banner's Perspective in a nutshell
"Dude, why is this **** legal? I lose control of my character and basically lose a whole stock just because HE GRABBED ME? That's completely broken, and doesn't show skill, it just shows a severe imbalance in the game. Marth already has an advantage on Lucas, so why make the MU horrendous? At least let's make a fight of out it. We already correct imbalances and other uncompetitive things in the game with our rules, so why not infinites? We even have a ledge grab limit, with a unique limit for MK! That's no less artificial than banning infinites. We may play to win, but how is abusing an imbalanced mechanic worthy of victory? We may as well make Hyrule Temple legal. It tips the scales significantly in certain characters' favors, just like infinites!"
The Infinite User/Supporter's Perspective in a nutshell
"Hey, I'm only using all the tools my character has at his disposal to win. This isn't a glitch, it's just the way the game's physics work. Why should my character's actions be limited to accommodate solo mainers of certain characters? It's the player's fault for picking and only sticking to unviable characters. Nobody is forcing them stay that character for that bad MU, so learn someone else for the MU or just accept the disadvantage and don't get ****ing grabbed. In this game, we play to win. The characters who can infinite you are far more defeatable than a MK with no LGL. Even with the ban, the former victims still have other problems (like other bad MUs) that will prevent them from moving up much in terms of tournament viability."
