well i've never personally gotten wobbled before lol so my opinions aren't based on personal experience.
the fact that it takes longer makes it all the more annoying.
I shouldn't have to play Rainbow Cruise or Pokefloats everytime i face Ice climbers.
The difference between Shine Spiking and Wobbling is that shine spiking requires timing, and it requires a set up, and its generally easy to avoid, not to mention, the slight possibility of whiffing, which could lead to a death, or lead to you being very vulenerable around the edge.
Wobbling requires one grab. A grab, which is a basic maneuver. that almost certainly occurs several times in every smash bros. game played ever.
People were mad enough when Chu Dat discovered the DownThrow Dair chain...much less one that goes, -> A, A, A, A, A....
Jigglypuff's rest is move that's balanced because you generally die if you miss, plus you have to be so close to your opponent for it to land that its a basically "take it when the chance comes" type move. IC's could with all practicality base their entire game around landing the wobble. and grabbing in general is a much bigger part of the game than the rest. It's not something you have to "wait for".
Shine spiking is easy for us because we've practiced it. I've only RECENTLY begun landing shine spikes in battle. its not really "easy". Example: Find a scrub, tell him how to shine spike, see if he can do it. He won't be able to on a consistent basis. On the other hand, tell that scrub how to wobble. Pressing A over and over again he'll be able to do.
Swallowcides result in Kirby losing a stock as well, that doesn't compare. If Icey's lost a stock when they wobbled, no one would consider banning it.
The easiness of it is the biggest factor to me. The fact that its so easy makes it virtually impossible to screw it up. That's why i don't mind things such as a waveshine inifinite, because its incredibly difficult to do effectively without tons of practice. Any old noob could pick Ice Climbers, learn how to land grabs, learn how to wobble, and start placing in tournaments. obviously high level people will defeat them, but its just a hugely unbalanced advantage in most cases.
Focusing on killing Nana is the counter to the wobble, but to me it's just ******** in general to play in order to avoid ONE killer move that guarantees your removed stock..
That's like saying, just kill Nana to avoid the Freeze Glitch, it so easy just gimp Nana. i mean, sure i could, but still.
