I just wanted to make sure it was specific. Stalling is broken. However, stalling is generally universally agreed to be banned. The problem lies in that a few of the specific tools that allow metaknight (actually applies to a few characters, but mostly MK) to stall are also capable of being used in general gameplay. If you allow them he can stall, if disallow them it potentially hurts his gameplay. However I think its silly when people say things like:
1. We're attempting to intentionally restricting his natural skill
-No, the intention is to restrict his ability to stall. Everything else is a side affect.
2. Adding lgls is the same as preventing akuma from kicking.
-If Akumas kick allowed him to potentially stall the entire match, then yes. However this seems unlikely.
3. LGL's cause a slippery slope, whats to prevent us from banning other moves/tactics?
-The amount tactics/options that can be considered anywhere close to stalling, even for metaknight, is very limited. Ive never heard a serious attempt to limit anything else on metaknight that didnt in some way relate to stalling.
tl;dr, everything in regards to limiting metaknight revolves around stalling, not limiting his natural 'broken' skill.
